Question

Simplify by combining like terms: 5x + 3x + 10x

Answer 1

Answer:

18x

Step-by-step explanation:

Since all 3 are monomial terms with the same variable, we can add them together:

5x + 3x = 8x + 10x = 18x

Answer 2

Answer: 18x

Explanation: The three parts of this expression, +5x, +3x, and +10x are called terms and the numbers in front of the variables, +5, +3, and +10 are called coefficients.

Because the variables, x, x, and x are identical,

the three terms in this problem are called like terms.

Like terms can be added together

by simply adding their coefficients.

So in this problem, since 5 + 3 + 10 is 18, 5x + 3x + 10 is simply 18x.
