Question

Use inverse operations and properties of equality to isolate the variable m+31=307

Answer 1

`m = 276`

Step-by-step explanation

The given equation is

`m + 31 = 307`

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

`m + 31 + - 31= 307 + - 31`

Simplify;

`m +0= 307 - 31`

`m = 276`
