I don't understand most of your question -- but to solve this equation:
5x + 5=15
First, subtract 5 from each side of the equation so that you get the unknown on one side and the known on the other.
5x + 5 - 5 = 15 - 5
5x = 10
Next, divide both side of the equation by 5 to find the value of x.
x = 2
You can prove it by substituting 2 for x in your original equation.
