Example: Solve the equation: x1/2 = 3/2. Solution: The unknown quantity is on the L.H.S. of the equation, and 1/2 has been subtracted from it. To remove 1/2 from L.H.S., we must do the inverse operation of subtraction, i.e., addition. Hence adding 1/2 to both sides of the equation, we get:
x  1/2 + 1/2 = 3/2 + 1/2
Verification: Substituting x=2 in the equation, Directions: Solve the following equations. Also write at least ten examples of your own and solve for the unknown variable.
