Solving One-Step Equations:

**Variable**- Is a letter that represents an unknown number in algebra Ex. a, g, x, n

**Constant**- Is the integer in an expression or equation Ex. x + 6

**Equation**- Has an equal sign and has only one possible answer Ex. 2x = 6

**Expression**- Is a pattern and has many different answers Ex. 2x

**Alge Tiles:**

To solve a one-step equation, the first thing you need to do is isolate the variable. To isolate the variable you need to get rid of the constant by using a zero pair or cancelling it out by using the opposite operation.

The next step is to balance it, which means whatever you do on one side of the equation sign, you have to do it on the other side of the equation sign.

The last step is to verify which is simply checking if your answer is correct.
