Step-by-step explanation:
The solution of the equation is x = 2
Step-by-step explanation:
The original equation is

We solve it using the following steps:
1) We apply the addition property of equality: by adding the same factor on both sides of the equation, the equation does not change.
In this case, we add +10 on both sides, and we get:

2) We apply the division property of equality: by dividing both sides of the equation by the same number (different from zero), the equation does not change.
In this case, we divide both sides of the equation by 5, and we get:

Therefore, the solution of the equation is
