Question

Using the formula C= 5/9(F - 32), find the Fahrenheit temperature when the Celsius temperature is 45º.

Answer 1

remember this one it is easier

f=1.8C + 32
F=1.8(45) + 32
F= 113

we can do it your way also

45= 5/9(F-32) mult both sides by 9/5
45(9/5) = F-32
81=F-32 add 32 both sides
113 = F
