You would subtract y on both sides so z-y then you get x=x. I think I hope this helps.

Answer:

c = 150p + 1000

Step-by-step explanation:

We know the variable cost is 150 per phone, so the total cost will be ...

c = 150p +b . . . . for some value b

We also know the value of c for 8 phones, so we can find b:

2200 = 150(8) + b

2200 -1200 = b = 1000

Then the desired equation is ...

c = 150p + 1000
