Answer: x = 27.5

Explanation:

We cannot solve for y in the equation, since we are only given an x value.

Given:

7x + 10 = 3x + 120

Subtract 3x from both sides of the equation:

4x + 10 = 120

Subtract 10 from both sides of the equation:

4x = 110

Divide both sides of the equation by 4:

x = 27.5
