Answer:
z = -2
Step-by-step explanation:
7z + 4 - 9z = 8 (The first step is to combine like terms, so 7z -9z = -2z)
-2z + 4 = 8 (Subtract 4 on each side)
-2z = 4 (Divide each side by -2)
z = -2
You can plug -2 back in to check, and you get:
7(-2) + 4 -9(-2) = 8
-14 + 4 + 18 = 8
8 = 8
Hopefully, this helped. Good luck!
