First let's try a Two-Step Equation.

Ex. 2x + 4 = 4

But first, let's write some facts about those numbers first.

This Number 2 in 2x is called a

**. The Coefficient is by the letter, which is called a**

*Coefficient***The Variable represents an unknown number. We won't know the number until after we solve the equation. The Coefficient is a letter that is used to multiply a variable. You can cancel it by using the opposite integer. The Constant is the factor of the Equation that never changes.**

*Variable.*2x + 4-4 = 4-4 =

__2x__=

__0__so x = 0.

Now we verify.

2x + 4 = 4

2(0) + 4 = 4

0 + 4 = 4

**4 = 4**

Now I will show how to divide with fractions in algebra.

Let's list some points down first.

- Isolate
- Cancel the constant with a zero pair
- Balance
- Cancel, divide with multiply
- Balance again
- Simplify
- Verify

x/4 + 5 - 5 = 10 - 5

__5x__= 5

4

x = 20

x/4 + 5 = 10

20/4 + 5 = 10

5 + 5 = 10

**10 = 10**

Now let's try Distributive Property.

2 (x + 3) = 10

2 groups of x + 3 = 10

x + 3

x + 3

**2x + 6 = 10**

Now you solve it using two step equation.

2x + 6 - 6 = 10 - 6 = 2x = 4 Divided by 2

x = 2

Now Verify.

2x + 6 = 10

2(2) + 6 = 10

4 + 6 = 10

**10 = 10**
