A common technique for simplifying algebraic expressions. When combining like terms, such as 2x and 3x, we add their coefficients. For example, 2x + 3x = (2+3)x = 5x.

Adding like terms is a fundamental concept in algebra. Coefficients are the numbers in front of variables, and they can be added when the variables are the same.

In this lesson, we learned how to add and subtract variables, like apples (a) or x's. We discovered that when we combine or take away the same variable, we can simply count them up or down. For …

Learn how to rewrite algebraic expressions by combining like terms. The expressions in this video have decimal and fraction coefficients.

We can only combine terms that have the same variable. That means we could combine an x with a 3x, because x is the variable in both of those terms, but we cannot combine a 4x with a 2xy.

Adding like terms is a fundamental concept in algebra. Coefficients are the numbers in front of variables, and they can be added when the variables are the same.

In this lesson, we learned how to simplify algebraic expressions by combining like terms. We focused on understanding the intuition behind adding and subtracting coefficients of the same variables.

Simplify algebraic expressions by combining like terms. Coefficients on some terms are negative.

The key realization here is to realize that we can't combine things that are different from one another. And you must also learn or master how to distribute so you can solve these problems

Practice combining like terms for expressions that have rational coefficients. This requires adding and subtracting fractions.
