way to many numbers for me... how do you solve for x?????

Rewrite the equation as follow:\n(2x+7){(x-7)+(2x-3)} -(2x-1)(3x+1)=-1\n(2x+7)(3x-10)-(2x-1)(3x+1)=-1\n(6x^2+21x-20x-70)-\n(6x^2-3x+2x-1)=-1 =>\n(6x^2+x-70)-(6x^2-x-1)=-1\n(note: x^2 means x to the power of 2)\nRe-group:\n6x^2-6x^2+x+x-70+1=-1\n              2x-69=-1 \n=> 2x=68 => x=34

I'd set it up like this...\n36      80\n--   =  --\n n      100\n\ncross multiply and solve for n

umm..are you missing an equals sign somewhere or am i really dumb? how do you figure out what x is unless you have both sides of the equation?

We can use faux-algebra to solve these. You probably haven't taken algebra yet. With algebra these would be extremely easy to solve. It's why algebra was invented.\n\na. 16 x ___ has to be -42, because if we add 51 to it we get 9. Thus, ____ has to be -42/16, or -21/8.\n\nb. 2 x ____ has to be 22 - 9 x _____, because if we subtract 8 from it we get 14 - 9 x ____. And 22 has to be 11 x ____, because if we subtract 9 x ____ from it we get 2 x ____. Thus, ____ has to be 22/11, or 2.\n\nc. 9 x ___ has to be 3 x ____ + 3, because if we add 2 to it we get 3 x ___ + 5.  And 3 has to be 6 x ____, becuase if we add 3 x ____ to it we get 9 x ____. Thus, ____ has to be 3/6, or 1/2.\n\nWith algebra, no such thinking would be required. You just plug in the formulas and grind away. You'll see when you study algebra.

I hate to tell you, but I don't think there is an algebraic method for arriving at a value for x. Sometimes, this can be the case, in which case all you can do is find a numeric approximation, here around x=1.0587...\n\nI'll see if another user can prove me wrong, but I'm going to go with there's no way to solve this problem using analytic methods.

X = 24/Y  Just start plugging in Y and getting X, there are lots of possibilities, unless you restrict it to just whole numbers.

12 simply place the 1 where the x is\n\n(1+3)(1+2)\n4*3\n12

Use log you will find\n\nor put\n\nx=3.597285024\n\nIts done

Let x = the number you are looking for.\n\nSo, 3x + 7 = 52, which is easily solvable for x as follows:\n\n3x + 7 = 52\n\n3x = 45\n\nx = 15\n\n~ ♥ ~

(x+7)(x+3)\n(x-11)(x+2)\nforget this one.  its AC factoring though\nthis ones AC too

okay well pretty much you have to solve for  x\nso inorder to get X by itslef you have to -4 from -8 like so:\n2x + 4-4 = –8-4\n2x=-12\nnow you still have 2X but now you can divide the 2 into -12\nx= \nI won't give you the answer but you should be able to find the answer!!!

an enormous number..!!!\ncalculator gave up

What you want to do is progress till the x is the only thing on one side of the equation; so\n\nget the 7 on the other side by adding 7 to each side of the equation:\n3x-7+7=26+7; this comes out to \n3x=33\n\nstill with me?   you have to do the same thing to both sides of the equation to keep it equal, so since you had to add seven to get rid of minus seven, you also have to add seven to the other side.\n\nnow you have  3x=33 and you need to get rid of the 3 multiplier, so now you will divide each side of the equation by 3:\n3x /3=33/3, or\nx=11\n\nto check for accuracy, just plug your answer, 11, back into the original equation and make sure it works:\n3times11  -7= 26.    \n\nsee? it's not so hard when you take it step by step.  in a little while you'll be solving these in your head.\n\nblessings!\ncryllie

I prefer "long" multiplication but it doesn't line up as well...\n\n3x^2 + 7x - 6\n* _____x+12\n--------------------  Multiplying term by term\n_____36x^2 + 84X - 72\n3x^3 + 7x^2 - 6x\n--------------------------------  Add term by term\n3x^3 + 43x^2 + 78x - 72   <--  final answer

D\n\nEither is sufficient.  \n1) will lead to 2 equations,2 unknowns which yield a unique solution for x and y:  x=y+1, x+y=77, therefore x=39, y=38.  xy=1482 \n\n2) If the sum is 77 and x and y have the same tens digit, then there are two solutions for {x,y}, namely {38,39} and {39,38}, however the product xy is the same. xy=1482

Let x = 0.99999999999999...\n\nThen,\n10x = 9.99999999999999.....\nSubtract x\n\n10x=9.99999999999999.....\nx = 0.99999999999999.....\n\n9x = 9\nTherefore \nx = 1\nand\n0.99999999999999999..... = 1\n\nQED ^_^
