Using this and the knowledge that 32° F = 0°C and 212°F = 100°C, find an equation that computes Celsius temperature in terms of Fahrenheit temperature; i. e., an equation of the form C = “an expression involving only the variable F.” c=(f-32)/1.8

Likewise, find an equation that computes Fahrenheit temperature in terms of Celsius temperature; i. e. an equation of the form F = “an expression involving only the variable C.”
f=1.8c+32
