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
