Um do u guys know what dpe ape mpe and spe means please i don't get it its like when u do 2step equations like 5x + 5=15

Answer 1

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.
