Question

solve for a. 2(a - 5) = -2 a = ?

Explanation:

Step1: Expand the left - hand side

$2(a - 5)=2a-10$, so the equation becomes $2a - 10=-2$.

Step2: Add 10 to both sides

$2a-10 + 10=-2 + 10$, which simplifies to $2a = 8$.

Step3: Divide both sides by 2

$\frac{2a}{2}=\frac{8}{2}$, so $a = 4$.

Answer:

$4$
