Solve for q.

-15 - 18q = - 20q + 15

q =

q = 15

Step-by-step explanation:

→First, add 18q to both sides:

-15 - 18q = - 20q + 15

-15 = - 2q + 15

→Subtract 15 from both sides:

-30 = - 2q

→Divide both sides by - 2:

15 = q

We first want to get q on its own then solve like shown:

-15-18q=-20q+15

Now add 15 to both sides and add 20 q to both sides.

2q=30

Now divide 30 by 2.

q=15
