simplify the algebraic expression

18x+6x

The simplified expression is 24x.

To simplify the algebraic expression 18x + 6x, you can combine like terms.

18x means 18 times x, and 6x means 6 times x. Since they have the same variable (x), you can add their coefficients (18 and 6) together.

18x + 6x = (18 + 6)x

Adding the coefficients, 18 + 6 = 24, so the simplified expression is:

24x
