To solve for x:
<span>C=85x+60 subtract 60 from both sides
</span>
<span>C - 60=85x+60 - 60
C - 60 = 85x now divide by 85 both sides
(C - 60)/85 = x
So we can write:
</span>
<span>C=85x+60 subtract 60 from both sides
</span>
<span>C - 60=85x+60 - 60
C - 60 = 85x now divide by 85 both sides
(C - 60)/85 = x
So we can write:
</span>
