2x-10x+70=10
Use the distributive property to multiply -5 by 2x-14.
-8x+70=10
Combine 2x and -10x to get -8x.
-8x=10-70
Subtract 70 from both sides.
-8x=-60
Subtract 70 from 10 to get -60.
x=\frac{-60}{-8}
Divide both sides by -8.
x=\frac{15}{2}
Reduce the fraction \frac{-60}{-8} to lowest terms by extracting and canceling out -4.
