Answer:
8x - 5
Explanation:
7x - (- x + 5) = 7x + x - 5 = 8x - 5
This is because when you eliminate a bracket, you multiply and the rules of multiplication state that
- × - = +
- × + = -
8x - 5
assuming you require to simplify the expression
7x - (- x + 5) ← distribute terms in the parenthesis by - 1
= 7x + x - 5 ← collect like terms
= 8x - 5
