If a variable appears more than once, simplify the variables. What do you do if the same variable appears more than once in the equation? Though this situation may seem tricky to solve, you can actually treat variables how you'd treat normal numbers — in other words, you can add them, subtract them, and so on as long as you only combine variables that are alike. In other words, x + x = 2x, but x + y doesn't equal 2xy.- For example, let's look at the equation 2x + 1x = 9. In this case, we can add 2x and 1x together to get 3x = 9. Since 3 x 3 = 9, we know that x = 3.
- Note again that you can only add the same variables together. In the equation 2x + 1y = 9, we can't combine 2x and 1y because they are two different variables.
- This is also true for when one variable has a different exponent than another. For instance, in the equation 2x + 3x2 = 10, we can't combine 2x and 3x2 because the x variables have different exponents. See How to Add Exponents for more information.
