Answer 1

Step-by-step explanation:

Given that:-

3 m + 7= 163m+7=16

To find:- The value of the expression,

To solve this expression, we have to use the transposition method:

As we have,

=> 3 m + 7= 163m+7=16

Subtract 77 on both sides,

=> 3 m + 7-7= 16-73m+7−7=16−7

Simplifying it further, we get

=> 3m = 93m=9

Divide both sides by 33 ,

=> m = 3m=3

Hence, the required solution is 3.
