Answer:
x = 2
Explanation:
given the equation
3x + 2(6 - x) = x + 4(x + 1) ← distribute parenthesis on both sides )
3x + 12 - 2x = x + 4x + 4 ← collect like terms on both sides
x + 12 = 5x + 4 ( subtract 5x from both sides )
- 4x + 12 = 4 ( subtract 12 from both sides )
- 4x = - 8 ( divide both sides by - 4 )
x =
, that is
x = 2
