Answer 4

70-4q=80

Answer 5

-4q = 10

q = -10/4

q = -5/2

Answer 6

70 - 4q = 80
-4q=10
q=-10/4
q=-5/2 or -2.5

Answer 7

Combine the like terms. -q + -q + -2q, which is -4q
Now you have 70-4q = 80
By using inverse operations, subtract 70 from each side, which will leave you with
-4q = 10
Divide each side by -4 and you will get q = -10/4 or -5/2

Answer 8

-4q=10
q=-5/2
