Answer:
x = 1.5
Step-by-step explanation:
4X + 1/2(4X + 6) =12
Distribute
4x +2x+3 = 12
Combine like terms
6x+3 = 12
Subtract 3 from each side
6x+3-3 =12-3
6x = 9
Divide each side by 6
6x/6 = 9/6
x = 3/2
x=3/2 or x=1.5
4x+2x+3=12
take 3 from both sides leaving you with 4x+2x=9
6x=9
simplify to get 2x=3
divide both sides by two to get x=3/2
x=1.5
