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>
I hope that

Answer:
-10
Step-by-step explanation:
x+75=180-(x+125)
2x=-20
x=-10
written answer in the picture
3t-18t+4=-26
first you want to move the 4 to the other side of the equation so subtract that from both sides of the equation which gives you this 3t-18t=-30.
Next you would combine the like terms that are on the left side of the equation giving you -15t=-30. Now you want t by itself so you divide both sides by -15 which would give you t=2
