First, add 7 to both sides of the equation so it would be;

2−7=−5+14

2−7 + 7=−5+14+7

To simplify this it would be:

2=−5+21

Add 5 to both sides, it would look like this:

2=−5+212+5=−5+21+5

To simplify it would be;

7=21

Divide both sides of equation with once again, the same number

7=21  77=217

Simplify it;

=3

Therefore your answer is;

=3
