 Example: Solve the equation: 9x = 36 Solution: The unknown quantity x is on the L.H.S. and is multiplying by 9. To remove 9 from L.H.S., we must do the inverse operation of multiplication i.e., division. Dividing both sides by 9, we get 9x/9 = 36/9 x = 4 Verification: Substituting x=4 in the equation L.H.S.Þ 9x = 9 * 4 = 36 = R.H.S. \ x = 4 is the solution. Directions: Solve the following equations. Also write at least ten examples of your own and solve for the unknown variable.
