options are....


(a) 1

(b) 2

(c) 3

(d) 4
​

Answer 1

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.
