The following figure shows how to solve two-step equations. Scroll down the page for more examples and solutions.

In order to solve two-step equations, we need to work backwards with regards to the order of operations. We would perform the addition & subtraction before multiplication & division.

- Add or subtract to isolate the variable term.
- Multiply or divide to solve for the variable.
- Check your solutions.

**Example:**

Solve 3x – 2 = 16

**Solution:**

In the equation 3x – 2 = 16, notice that the variable is being multiplied and has a term
being subtracted. To isolate the variable, we need to add 2 to both sides and then divide both
sides by 3.

3x – 2 = 16

3x – 2 + 2 = 16 + 2 (add 2 to both sides)

3x = 18 (simplify)

x = 6 (divide both sides by 3)

Check:

3x – 2 = 16

3 • 6 – 2 = 16 (Substitute x = 6 into the original equation)

**Example:**

Solve

**Solution:**

Consider the equation, . To isolate the variable, we need to subtract 2 from both sides and then multiply
both sides by 4.
