**Numerical Coeffecient**- A number that

__multiplies__the

__variable.__

*e.g.*

__2x__

If you aren't sure what those mean, then here's an example

1/2. Isolate the variable by using the opposite operations. a + 1 - 1 = 3

3. Simplify. a = 2

Now to check your answer.

a + 1 = 3

Take away the variable and put in the number of the variable.

2 + 1 = 3

Simplify. 3 = 3.
