Question

Combine like terms to create an expression equivalent to: n +n + n + y + y

Answer 1

`3n+2y`

Explanation:

LIKE TERMS: TERMS WHOSE VARIABLES AND EXPONENTS ARE THE SAME.

`(1)n+(1)n+(1)n+(1)y+(1)y`

When combining variables that do not have coefficients, there is always an invisible '1' in front of the variable.

`(1)n+(1)n+(1)n = 3n.`

`(1)y+(1)y=2y.`

`3n+2y.`
