Solve for a. 7a - 2b = 5a + b a = 2b a = 3b a = b a = b

larisa [96]

$\\
\text{Consider the equation}\\
\\
7a-2b=5a+b\\
\\
\text{to solve for a, we will first add 2b both sides. so we get}\\
\\
7a-2b+2b=5a+b+2b\\
\\
\Rightarrow 7a=5a+3b\\
\\
\text{now subtract 5a both sides. so we have}\\
\\
7a-5a=3b\\
\\
\Rightarrow 2a=3b\\
\\
\text{divide 2 both sides to get}\\
\\
\Rightarrow a=\frac{3b}{2}$
