-5%281-5x%29%2B5%28-8x-2%29=-4-8x Start with the given equation.


-5%2B25x-40x-10=-4-8x Distribute.


-15x-15=-4-8x Combine like terms on the left side.


-15x=-4-8x%2B15 Add 15 to both sides.


-15x%2B8x=-4%2B15 Add 8x to both sides.


-7x=-4%2B15 Combine like terms on the left side.


-7x=11 Combine like terms on the right side.


x=%2811%29%2F%28-7%29 Divide both sides by -7 to isolate x.


x=-11%2F7 Simplify.
