You have the following equation:
7(x + 4) - 44 = x + 8
In order to solve for x, proceed as follow:
Expand the factor left side:
7x + 28 - 44 = x + 8
Simplify like term:
7x - 16 = x + 8
Subtract x and add 16 both sides:
7x - x = 8 + 16
6x = 24
Divide by 6 both sides:
x = 24/6
x = 4
Hence, the value of x is 4
