So we have the expression:

[tex](5x-2y+7)+(3x+y-8)[/tex]

Combine like terms:

[tex]=(5x+3x)+(-2y+y)+(7-8)[/tex]

Add:

[tex]=8x-y-1[/tex]

And we're done!

Answer:

8x-y-1

Step-by-step explanation:

First remove the parentheses

5x-2y+7+3x+y-8

Add 5x and 3x

8x-2y+7+y-8

add -2y and y

8x-y+7-8

Subtract 8 from 7

8x-y-1
