10%28-x-7%29%2B20=-5%282x%2B4%29 Start with the given equation



-10x-70%2B20=-10x-20 Distribute


-10x-50=-10x-20 Combine like terms on the left side


-10x=-10x-20%2B50Add 50 to both sides


-10x%2B10x=-20%2B50 Add 10x to both sides


0x=-20%2B50 Combine like terms on the left side


0x=30 Combine like terms on the right side


0=30 Simplify

Since this equation is never true for any x value, this means there are no solutions.
