Question

Add. (5x - 2y + 7) + (3x + y - 8)

Answer 1

8x-y-1

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

Answer 2

`=8x-y-1`

Explanation:

So we have the expression:

`(5x-2y+7)+(3x+y-8)`

Combine like terms:

`=(5x+3x)+(-2y+y)+(7-8)`

Add:

`=8x-y-1`

And we're done!
