Answer:
x = [tex]\frac{6}{4+a-2b}[/tex]
Step-by-step explanation:
Given
4x + ax = 2(bx + 3) ← distribute parenthesis
4x + ax = 2bx + 6 ( subtract 2bx from both sides )
4x + ax - 2bx = 6 ← factor out x from each term on the left side
x(4 + a - 2b) = 6 ← divide both sides by (4 + a - 2b)
x = [tex]\frac{6}{4+a-2b}[/tex]
