0=x+5

We need to get x by itself so -5 from both sides of your equation:

0-5=x+5-5

Note how this now gets x by itself

`therefore` -5=x

To check substitute your answer into your original equation so instead of  0=x+5, you will substitute x with -5

0=-5+5

0=0

This statement is true because 0=0

A)0=x+5

minus 5 on both sides

-5=x

to check plug -5 as x

-5+5=0

A)0=x+5

You need to move the variable on one side

-x=5

since you can't have a negative variable divide it by -1

therefore x=-5
