Simply move an unknown to one side, and known to the other. Then the number of the right divided by the number of standing by the unknown and this is the result.

N is a variable.

Solve linear equation as follows:
- Unknown move to one side of the equation, and the numbers on the other side of the equation,
- Multiply or divide both sides by a value in order to get the number of the unknown N,
- The transfer number or unknown to the other side of the equation, change the sign to the opposite.

-9+n/4=-7

Therefore: n/4=-7+9 (Notice that I had sent the negative 9 to the other side of the equation therefore it became positive.)

Therefore: n/4=2 (Notice that -7+9=2)

Therefore n=8 (Notice that I had to multiply both sides of the equation by 4 so that I could isolate n.)
