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
