Steps In Solving Variables in Equations
1. Isolate the variable (get the variable by itself)
2. Whatever you do on one side of the equal sign do
the same thing on the other side
3. Follow the math rules and don’t over think it!
4. Check your work
Example
The Problem:
n + 7 = 12
The Process:
1,2 - n+7-7=12-7
3. n + 7-7 =12-7
n + 0 = 5
The Solution:
n = 5
The Check:
4. 5 + 7 = 12
