3x-4x-\left(-8\right)=2x+3-\left(x-2\right)
To find the opposite of 4x-8, find the opposite of each term.
3x-4x+8=2x+3-\left(x-2\right)
The opposite of -8 is 8.
-x+8=2x+3-\left(x-2\right)
Combine 3x and -4x to get -x.
-x+8=2x+3-x-\left(-2\right)
To find the opposite of x-2, find the opposite of each term.
-x+8=2x+3-x+2
The opposite of -2 is 2.
-x+8=x+3+2
Combine 2x and -x to get x.
-x+8=x+5
Add 3 and 2 to get 5.
-x+8-x=5
Subtract x from both sides.
-2x+8=5
Combine -x and -x to get -2x.
-2x=5-8
Subtract 8 from both sides.
-2x=-3
Subtract 8 from 5 to get -3.
x=\frac{-3}{-2}
Divide both sides by -2.
x=\frac{3}{2}
Fraction \frac{-3}{-2} can be simplified to \frac{3}{2} by removing the negative sign from both the numerator and the denominator.
