can someone help me?

Answer: 18
Step-by-step explanation:
You first have to use the distributive property on the left side simplifying the problem to [tex]\frac{1}{2} x - 7 = \frac{1}{3}x - 4[/tex]. From here add the seven to both sides and subtract the 1/3x from both sides. This will give you 1/6x = 3 which equals 18.
