So lets add the x together and the numbers together. We will have this:
5+ 20-22-3x – 10.2-2x + 5 = 0
25-22-5x-10.2+5=0
Lets put the variables on one side and the numbers on the other side. Every variable or number that will change sides, will have their sign changed from a + into a - and vice versa.
5x=25-22-10.5+5
5x=-2.5
Divide both sides with 5.
5x/5 = -2.5 / 5
x = -0.5
