Question

Solve the literal question 2a-b.=8b-4a for a

Answer 1

Just good ole algebraic manipulation
$2a - b = 8b - 4a$
First, Let's Combine Common Terms

$(2a + 4a) = (8b + 1b) \\ 6a = 9b$
Now Let's Divide

$\frac{6a}{6} = \frac{9b}{6} \\ a = \frac{9b}{6}$
Let's Simplify That Fraction

$a = \frac{9}{6} \times \frac{b}{1}$
Answer

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