3-x=-\left(5-2x\right)
Variable x cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by x-2, the least common multiple of x-2,2-x.
3-x=-5+2x
To find the opposite of 5-2x, find the opposite of each term.
3-x-2x=-5
Subtract 2x from both sides.
3-3x=-5
Combine -x and -2x to get -3x.
-3x=-5-3
Subtract 3 from both sides.
-3x=-8
Subtract 3 from -5 to get -8.
x=\frac{-8}{-3}
Divide both sides by -3.
x=\frac{8}{3}
Fraction \frac{-8}{-3} can be simplified to \frac{8}{3} by removing the negative sign from both the numerator and the denominator.
