3/4X - 24 = -1/4X + 12
First put all the x's on one side and all of the numbers on one side.
(3/4X + 1/4X) = 12 + 24
X = 36

3/4x - 24 = - 1/4x + 12
4(3/4x) - 4(24) = - 4(1/4x) + 4(12)
3x - 96 = - x + 48
3x - 96 x = - x+ 48 + x
4x - 96 = 48
4x - 96 + 96 = 48 + 96
4x = 144
4x/4 = 144/4
x = 36
The answer is x = 36

¾x - 24 = -¼x + 12
¾x + ¼x - 24 = -¼x + ¼x + 12 --- Adding ¼x to each side...
1x - 24 = 12 --- We can drop the 1 in the 1x because (1)(x) = x...
x - 24 = 12
x - 24 + 24 = 12 + 24 --- Adding 24 to both sides...
x = 36
Answer: x = 36

3/4X -24 = -1/4X +12 multiply both sides by 4x
3-96x=-1+48x add 1+96x to each side
4=144x divide by 144
x=1/36
