5x-10=2x-12
Use the distributive property to multiply 5 by x-2.
5x-10-2x=-12
Subtract 2x from both sides.
3x-10=-12
Combine 5x and -2x to get 3x.
3x=-12+10
Add 10 to both sides.
3x=-2
Add -12 and 10 to get -2.
x=\frac{-2}{3}
Divide both sides by 3.
x=-\frac{2}{3}
Fraction \frac{-2}{3} can be rewritten as -\frac{2}{3} by extracting the negative sign.
