Answer:
C. 3
Explanation:
First, use the distributive property. Multiply 4x and 1 each by 2.
This gives us the equation 50 + 8x - 2 = 72.
Next, subtract 2 from 50 to get 48. Subtract 2 from 2 to cancel it out.
Then, we have 48 + 8x = 72.
Subtract 48 from both sides. This leaves 8x = 24.
Divide both sides by 8 to get x = 3.
