Answer

Explanation:

Step1: Move terms with a to one - side

Subtract 5a from both sides: $7a - 5a-2b=5a - 5a + b$ $2a-2b = b$

Step2: Move the non - a term to the other side

Add 2b to both sides: $2a-2b + 2b=b + 2b$ $2a=3b$

Step3: Solve for a

Divide both sides by 2: $a=\frac{3}{2}b$

Answer:

$a=\frac{3}{2}b$
