OK,as the first one is already done,I am doing the rest for you\n4(2x-6)=x+2 =>8x-24=x+2  =>8x-x=2+24  =>7x=26  =>x=26/3=8 2/3  (3) 2(x+5)+1=3(x-1)+4   =>2x+10+1=3x-3+4 =>2x-3x=-3+4-10-1  => -x=-4  =>x=1  (5)x+6=4(4x-1)   =>x+6=16x-4  =>x-16x=-4-6  => -15x=-10  =>x=-10/-15=2/3 [after reducing]

take out 4x first\n4x(x2-6x+8)\n4x(x-4)(x-2)

Answer 1:\n(4y + 2)/2 = 21\n4y + 2 = 21*2\n4y + 2 = 42\n4y = 42 - 2\n4y = 40\ny = 40/4\ny = 10\n\nAnswer 2:\na + 4 = 3a - 81\na = 3a - 81 - 4\na = 3a - 85\na - 3a = -85\n-2a = -85\n2a = 85 (The minus signs cancel each other out)\na = 85/2 (or) 42.5\n\nAnswer 3:\n146 = (36y + 2)/4 = 236.5?\nThis means that 146 = 236.5 which is never possible\nThis implies that the equation has no solution.

you can factor this easily\n2 numbers that add to -8  and multiply to -33    (-11 and 3)\n so then u just    do  (x-11)(x+3)    and  if the product=0, then 1 of them has to equal 0. so either x-11=0 so x=11      or x+3=0   and x=-3. so      the 2 answerz are     11,-3. you should try to do it yourself first instead of just askin for answers. if you cant easily factor it, then use the quadratic equation\n\nx = [-b +-   sqrt (b^2 - 4ac)]  / 2a\n\nand put in the values of a, b, c. in this case a is 1, b is -8  and c is -33. so you can do\nx = 8+- sqrt (8^2 - 4 (1) (-33))   /  2\n  = 8+- sqrt (64 +132) / 2\n  = 8+- sqrt (196) / 2\n  = 8+- 14 / 2\n  = 4+-7\n  = 4+7           or        4-7\n  =  11     or  -3

Plug in each of the four answers.  The only one that works is (2), because you get\n\n | 3 (-2/3) - 3 | = 5\n | -2 - 3 | = 5\n | -5 | = 5\n 5 = 5

take the length of the equal sides to be a,and the other side to be b\na=4b-8\n2a+b=29\nso 29-2a=b\nsubstitute for b\na=4(29-2a)-8\na=116-8a-8\na=116-8-8a\na=108-8a\n108=8a-a\n108=7a\na=15.428571428571428571428571428571(the 428571s repeat)

Ok...\nI see what you are doing...\nYou merely substitute the number in for x...\nso the problem becomes 6-2*(-1)\n6+2\n8

Factorize!\n4x (x^2-9) = 0\n4x (x+3) (x-3)\n\nyour solution is \nX = 0\nx= -3\nx= 3

Sorry a12b13n5! - I think you are wrong on this one\n\nq +14 =8q + 8x7 (multplying out the brackets)\nq + 14 = 8q + 56 \nq - 8q = 56 - 14 (seperating the 'q's and numbers)\n\n-7q = 42\n\nthen devide by -7 to get\nq = -6\n\nto check\n-6 + 14 = 8 = 8(-6+1) = 8(1) = 8

That is right. Just put them in a calculater to check. 2/9=0.22222222 and 8/36=0.2222222. Either they are wrong or you misinterpred the question and it was asking something else. The best way to solve a problem like that is to cross multiply. 2/9=8/? turns into 2*?=8*9.

Im guessing your solving for y... so make the problem 58=29Y.  Divide both sides by 29 and you get y=2
390719
so you have (1/2)a+a-(6/3)=4+(1/3)a\n\nadding like terms: (3/2)a-2=4+(1/3)a\n\nsubtract (1/3)a from (3/2)a and add two to both sides:\n(3/2-1/3)a=4+2\n(9/6-2/6)a=6\n(7/6)a=6\n\nnow solve and what do you get? :)
223041
uh..... no. Unless I am missing something, you substitute the 3 for 'x' and the 2 for 'y' and get 3+(3 x 2) = 3 + 6 = 9
