Example: Solve the equation x+6=8. Solution: The unknown quantity x is on the L.H.S. of the equation and 6 is added to it. To remove 6 from L.H.S., perform the inverse operation of addition i.e., subtraction. Hence subtracting 6 from both sides of the equation, we get x+66 = 86 x=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.
