Answer:
Step-by-step explanation:
3(5-q)+6=9 Remove the brackets
15 - 3q + 6 = 9 Combine the left
21 - 3q = 9 Subtract 21 from both sides
-3q = 9 - 21 Combine the right
-3q = -12 Divide by 3
q = -12/-3
q = 4
If you understand it, you can get the answer easier by dividing by 3 right at the beginning.
5 - q + 2 = 3
7 - q = 3
-q = -4 multiply both sides by - 1
q = 4
