What is the answer to this question

2x+20+5x+3x = 95+25

It's important to do the same thing to both sides in an equation so it stays equal,

so first you group like terms (x with x and #'s with #'s)

so

2x+5x+3x+20=95+25

10x+20=120

subtract 20 from both sides

10x=100

divide both sides by 10

x=10
