Answer:
q=13
Explanation:
First, you can multiply to distribute 2 over -9 and 4.
-18=2(-q+4)
-18=-2q+8
Then, you can subtract 8 from both sides.
-18=-2q+8
-26=-2q
Finally, you can divide -2 on both sides.
13=q
Now, you can check by plugging in 13 for the value of q in the original equation.
-18=2(-(13)+4)
-18=2(-13+4)
-18=2(-9)
-18=-18
Hope this helps you! :)
