hello!
so the answer that you put there is actually wrong and i'll tell you why and how to do it
so since you are adding the two:
-8x + 9x = x (so you got this part right)
-12 + 4 = -8 (this is where you got it wrong, -12 added 4 goes up in value to -8)
so the final answer is x - 8
i hope this helped and have a nice day!

Answer:
Step-by-step explanation:
you ate 3
you paid $9.45 for the 3
to find the cost of the whole pizza you need to know how much each slice costs so
9.45 / 3 = $3.15 a slice
so each slice is $3.15 and there are 8 slices and you need to know how much they cost altogether so
3.15 * 8 = $25.20
