Answer:

-5x + 2y + 5x - 8y = -6y

Step-by-step explanation:

Like terms are terms whose variables (and their exponents) are the same.

[tex]-5x+2y+5x-8y[/tex]

We have the terms:

[tex]-5x;\ 2y;\ 5x;\ -8y[/tex]

Like terms:

[tex]-5x\ \text{and}\ 5x,\ 2y\ \text{and}\ -8y[/tex]

Combine like terms:

[tex](-5x+5x)+(2y-8y)=0x+(-6y)=-6y[/tex]
