Solve Simple Algebraic Expressions

In this lesson, we will learn how to solve simple algebraic expressions. An algebraic expression is a mathematical phrase that includes numbers, variables, and operation symbols.

What is an algebraic expression?

For example, 2x + 3 = 7 is an algebraic expression. Here, x is a variable, and we need to find the value of x that makes the equation true.

Example 1:

In the equation 2x + 3 = 7, we can solve for x by subtracting 3 from both sides of the equation:

2x = 4, then divide both sides by 2 to find that x = 2.

Example 2:

In the equation 3y - 5 = 10, add 5 to both sides:

3y = 15, then divide both sides by 3 to find that y = 5.

Now, let's solve some algebraic expressions!
