I will try to explain step by step....\n\nA) x-2/3 + x+3/4=5/6\nFirst you would place like terms together;\nx+x-2/3+3/4=5/6\nThen try to make all the denominators equal.  Do this by thinking of what the denominators can all go into.  In this case, they can all go into 12 using whole numbers.  Since multiplying by 1 doesn't change the value, you can do that by multiplying the top and bottom of each fraction by the same number.  \n  So the -2/3 would all be multiplied times 4/4 giving you -8/12.  The 3/4 would all be multiplied times 3/3 giving you 9/12.  The 5/6 would all be multiplied times 2/2, giving you 10/12.\n\nThe equation would now look like;\nx+x-8/12+9/12=10/12\n\nYou then combine like terms;\nx+x=2x\n-8/12+9/12= 1/12\nSo your equation is now;\n2x+1/12=10/12\n\nSubtract 1/12 from both sides;\n2x=9/12\n\nAnd divide by 2;\nx=4.5/12 or 9/24\n\n9/24=3/8\n\nSo, the answer to A would be x=3/8\n\nAs for B...I'm not to good at word problems, sorry :)\n\n\nAnd NS in line 3 of your work, it should be -8/12 because -2*4= -8 not 8

a. 12           16/4=4   4x3=12      or     3/4= 0.75   0.75x16=12\n\nb. first u need to find a common denominator so put it all in fractions  3 x ? = 12        we need to change the 1 to a 5 so we\n                5    ?     1         multiply by 5, since we multiplied the\n                                        1 then we need to multiply the 12 by the \n                3 x ? = 60         same to get 60 so now we have...\n                5    ?     5\n                                             so now we just have to fill in the ? by multiplying 3x20=60    and 5x1=5    so 20over one is simply 20\nso (3/5x20=12)\n\nc. well this depends if the numbers have to be same, if not then just put in any number for the first since ( ), multiplication and division are always done first and then fill in the rest to match\n\nso lets get the first one down to a lower number so it will be easier  25(8 x -1 + 10)  8 x -1 = -8   (-8+ 10) = 2\n(25 x 2 = 50)      since the answer is 3 the 50-3=47 so now we have to figure out what number to put in to get 47\nso lets reverse the equation 47 / 2 = 23.5 and so we add 1  24.5\n\n2(24.5-1)=47      50-47=3\n\nso the final equation is 25(8 x -1 + 10) - 2(24.5 -1) = 3

4x+3/2-2x-2=3-x-4/3+2x-5        then you add everthing up\n\n2x-1/2=x-3and2/3           Sorry for the and....i didn't want it to look like 32 divided by 3....it's 3 and 2/3\nmultiply each side by 6...\n12x-3=6x-22\nThen you have to simplify \n6x=19  Divide each side by 6 to get the answer\nx=19/6\nI'm pretty sure but im not absolutly sure....

multiple both sides of equation by x to give\n\n2x     -     1x      =    1x\n---         ---          ---\n3            x            5x\n\nwhich resolves to:\n\n2/3x -1 = 1/5\n2/3x = 1 + 1/5 = 1.2\nx=(1.2 *3)/2 = 1.8

-2x - 2 1/5\nIf I am not mistaked.

(1/2)3=   do what's in the parenthesis first.  1/2 equals 0.5  \nthen what's in the parenthesis times 3, so 0.5 times 3 equals 1.5

the word 'of' denotes, refers, to multiplication so\n2/3 of 1/3 = 2/3*1/3 = 2/9\n\nthey are all correct
