Combine like terms to create an equivalent expression.
Paha777 [63]

The equivalent expression of -\dfrac65-\dfrac23v+\dfrac{4}{15}+\dfrac13v is -\dfrac{15}{15}-\dfrac{v}3

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

-\dfrac65-\dfrac23v+\dfrac{4}{15}+\dfrac13v

Collect like terms

-\dfrac65+\dfrac{4}{15}+\dfrac13v-\dfrac23v

Evaluate the like terms (take LCM)

\dfrac{-6 * 3 + 4}{15}+\dfrac{v - 2v}3

Evaluate the like expressions

-\dfrac{15}{15}-\dfrac{v}3

Hence, the equivalent expression of -\dfrac65-\dfrac23v+\dfrac{4}{15}+\dfrac13v is -\dfrac{15}{15}-\dfrac{v}3
