Hope this helps!

Answer 2

Answer:

x = 8

Step-by-step explanation:

Reorder the terms:

15 + 5x = 55

Solving

15 + 5x = 55

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 5x = 55 + -15

Combine like terms: 15 + -15 = 0

0 + 5x = 55 + -15

5x = 55 + -15

Combine like terms: 55 + -15 = 40

5x = 40

Divide each side by '5'.

x = 8
