Combining like terms4

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 4y are not.

To combine like terms, add or subtract the coefficients of the terms that have the same variable. For example, in 2x + 3x, you add the coefficients (2 + 3) to get 5x.

The result is 13x + 1.

The result is -5b - n + 12.

The result is 7c + 5.

The result is 8x + 5.

The result is 9a - 2b.

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 4x, 4 is the coefficient.

To simplify an expression means to combine like terms and reduce it to its simplest form.

Like terms have the same variable and exponent, while unlike terms do not. For example, 2x and 3x are like terms, but 2x and 3y are unlike terms.
