Question
The equation given below is followed by the value of the variable. Decide whether this value is the solution to that equation.
9m = 81, m = 3, 9, −3
Solution
9m = 81, m = 3, 9, −3
9m = 81
Dividing both sides by 9
⇒ `(9"m")/9 = 81/9`
⇒ `"m" = 81/9`
⇒ m = 9
Hence, m = 9 is the solution of the equation.
