Like terms have the same variable (or have no variable). In this expression you have two sets of like terms: Those with x, and those with y
Those with x: 5x, -x, 2x
Add the coefficients: (5-1+2)x = 6x
Those with y: 7y, -2y
Add the coefficients: (7-2)y = 5y
6x+5y is the answer.
Hope this helps.

Rearrange the values:
5x+2x-x+7y-2y
6x+5y

5x + 7y - x - 2y + 2x
(5-1+2)x+(7-2)y
6x+5y

First get together all the like terms
(5x-x+2x)+(7y-2y)=
6x+5y

5x+7y-x+2x=
5x-x+2x= 6x
7y-2y=5y
so the answer is 6x+5y

5x + 7y - x - 2y + 2x = 6x + 5y

rearrange equation:
5x+2x-x-2y+7y
now add/subtract all x's and y's
=> 5x+2x=7x-1x=6x
=> -2y+7y=5y
answer: 6x+5y

Combine like terms (x's to x's & y's to y's):
6x + 5y
