Combine the like terms to create an equivalent expression. 5x-x
nexus9112 [7]

Answer:

4x

Step-by-step explanation:

Like terms are terms that share the same variable (or base) and the same exponents.

5x and x are like terms in that they share the variable x but the coefficients are different.

To combine like terms you would look at the sign (in this case, a subtraction sign) and subtract the two coefficients.

There is an imaginary 1 in attached to x, so you are basically subtracting 1 from 5.

5x - x = 4x

4x is equivalent to 5x - x.
