Algebra Equations

In this section of Algebra Homework Help website, we discuss how to solve algebra equations with additions and subtractions. You can solve algebra equations with additions and subtractions to get the variable of the algebra equations on one side of the equations by itself.

Let's examine the algebra equation below:

x + 10 = 20

Remember, the objective is to get the variable, x, on one side of the algebra equation by itself. To do this, we need to get rid of the +10 next to the variable x.

The question is how do you get rid of +10? The answer is simple, you subtract 10.

So, you have:

x + 10 - 10 on one side

Since you have just subtracted 10 on the left hand side of the algebra equation, you MUST do the same on the other side of the algebra equation. The key is to be consistent. Whatever you do to one side of the equation, you must do the same to the other side of the algebra equation. So, you now have:

x + 10 - 10 = 20 - 10

Therefore,  x = 10 is your answer to the algebra problem.
