Answer:
x = -10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6 (1/3x + 1/3) = 3 (x + 4)
(6)( [tex]\frac{1}{3}x[/tex]) + ([tex]\frac{1}{3}[/tex]) = (3) (x) + (3) (4) (Distribute)
2x + 2 = 3x + 12
Step 2: Subtract 3x from both sides.
2x + 2 − 3x = 3x + 12 − 3x
−x + 2 = 12
Step 3: Subtract 2 from both sides.
−x + 2 − 2 = 12 − 2
−x = 10
Step 4: Divide both sides by -1.
[tex]\frac{-x}{-1}[/tex] = [tex]\frac{10}{-1}[/tex]
x = -10
