4x-2\left(10-5x\right)=-64
Multiply both sides of the equation by 4.
4x-20+10x=-64
Use the distributive property to multiply -2 by 10-5x.
14x-20=-64
Combine 4x and 10x to get 14x.
14x=-64+20
Add 20 to both sides.
14x=-44
Add -64 and 20 to get -44.
x=\frac{-44}{14}
Divide both sides by 14.
x=-\frac{22}{7}
Reduce the fraction \frac{-44}{14} to lowest terms by extracting and canceling out 2.
