Answer:
35 + 7x
Explanation:
You cannot solve it because there is no equal sign. This is not an equation. This is just an expression, so you can simplify it, but not solve it. To simplify it, use the distributive property to multiply out the 5 by what is inside the parentheses.
7(5 + x) = 7 * 5 + 7 * x = 35 + 7x
