 Example: Solve the equation: x/6 = 4. Solution: The unknown quantity x is on the L.H.S., and is divided by 6. To remove 6 from L.H.S., we must do inverse operation of division i.e., multiplication. Multiplying both sides of the equation by 6, we get x/6 * 6 = 4 * 6 x = 24. Verification: Substituting x = 24 in the equation L.H.S. Þx/6 = 24/6 = 4 = R.H.S. \x = 24 is the solution. Directions: Solve the following equations. Also write at least ten examples of your own and solve for the unknown variable.
