Grade 7 - Mathematics
6.19 Solution of Simple Equations - III

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. x/6 = 24/6 = 4 = R.H.S.
\x = 24 is the solution.
