Constant: The integer in an algebraic expression or equation

When there are (-) multiply and divide cancel with the same integer

**Solving Step One Equations:**

1) Isolate the variable

2) Cancel the constant using zero pair

3) Balance, doing it to both sides

4) Verify to check

**Solving Step Two Equations:**

1. Isolate the variable

2. Cancel the constant

3. Balance

4. Simplify the variable

5. Balance

6. Verify

I found this "website" very helpful, maybe it will help you understand algebra more too.
