Example: The temperature in Celcius degrees 'C' can be changed to Fahrenheit degrees 'F' by the formula F = (1/5)*(9C+160). Make C the subject of the formula, then find C when F = 212 degrees. Solution: F = (1/5)*(9C+160) Multiply both sides with 5, we get 5F = 5*1/5*(9C+160) 5F = 9C+160 5F160 = 9C 5(F32) = 9C C = 5/9*(F32) If F = 212 degrees Substitute F value in above equation, we get C = 5/9*(21232) C = 5/9*180 C = 5*20 C = 100 degrees.
