Simple factorization here, well maybe not simple for you since you asked the question. It is okay though.
You simply add or subtract like terms. So first the 'x's: 8x + -5x. Dont let the negative freak you out. You simply subtract giving you 3x.
Next the 'y's: 7y+1y = 8y. So you are left with your final answer of 3x+8y

Multiply by 1 to remove brackets =8x+7Y-5x+y
8x+7y-5x+y
8x-5x+7y+y
Answer =3x+8y

First step combine your like terms
make sure you got the like terms like this
(8x-5x)+(7y+y)
Second step take the (8x-5x) thats equal to 3x
and (7y+y) that equals to 8y
third step you get the answer
make sure you got 3x+8y

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

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

add like terms
(8x + 7y) + ( -5x + y)
equals
8x + 7y - 5y + y
equals
8x -5x +7y +y
equals
3x +8y

The parenthases are put here to confuse you. Just add up the x's and the y's together.
8x - 5x = 3x
7y + y = 8y
then put them together:
3x + 8y
