Answer 1

First we subtract 5 to both sides. What's 20 - 5?

Answer 2

15

Answer 3

Yes, now we have:

3q = -2q + 15

Now we add 2q to both sides, what's 3q + 2q?

Answer 4

5q

Answer 5

3q + 5 = -q + 20
3q + 5) + -5 + 2q) = (-2q+ 20) + (-5 + 2g)
(3q + 5) + (2q - 5) = (-2g + 20) + (2q - 5) = ?

Answer 6

Yes..so that gives us:

5q = 15

Now divide 5 to both sides, what do you get?

Answer 7

1q=3?

Answer 8

Yep, you got it..3 is your answer.
