-4x+5=2x+3-1-\left(-2x\right)
To find the opposite of 1-2x, find the opposite of each term.
-4x+5=2x+3-1+2x
The opposite of -2x is 2x.
-4x+5=2x+2+2x
Subtract 1 from 3 to get 2.
-4x+5=4x+2
Combine 2x and 2x to get 4x.
-4x+5-4x=2
Subtract 4x from both sides.
-8x+5=2
Combine -4x and -4x to get -8x.
-8x=2-5
Subtract 5 from both sides.
-8x=-3
Subtract 5 from 2 to get -3.
x=\frac{-3}{-8}
Divide both sides by -8.
x=\frac{3}{8}
Fraction \frac{-3}{-8} can be simplified to \frac{3}{8} by removing the negative sign from both the numerator and the denominator.
