Answer:

7/2 or 3.5

Step-by-step explanation:

Break the bracket and you will get:

-15 = 5*3q - 5*10 - 5q

-15 = 15q - 50 - 5q

Add 50 to both side, we get:

-15 + 50 = 15q - 5q - 50 + 50

35 = 10q or rewrite as 10q = 35

Divide bith side by 10, we got:

q = 35/10 = 7/2 or 3.5

Hope this helped :3
