Answer:

$\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y=-10y-16+10$

Step-by-step explanation:

Given the expression

$\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y$

Remove the parentheses

$=-4y-16-8y+10+2y$

Group like terms

$=-4y-8y+2y-16+10$

simplifying

$=-10y-16+10$

Therefore, the equivalent expression with 3 terms for the expression is:

$\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y=-10y-16+10$
