Question

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

Answer 1

ANSWER

$m = 276$

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;

$m +0= 307 - 31$

$m = 276$
