C=5 (f-32) / 9 solve for f

9*C=9*5 (f-32) / 9

9C/5 = 5 (f - 32) / 5

(9/5) C = f-32

f = (9/5) C + 32

Since f

is on the right side of the equation, switch the sides so it is on the left side of the equation.

5 (f - 32) / 9 = c

Multiply both sides of the equation by 9 : 5 (f - 32) c x 9

simplify the right side 5 (f - 32) = 9c

Then simplify the left side 5f - 160 = 9c

add - 160 to both sides of the equation 5f = 150 + 9c

Divide each term by 5 and then simplify

f = 32 + 9c (over) 5
