See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

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

Next, group like terms:

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

Now, combine like terms:

#(5 + 8)x + (3 - 7)y#

#13x + (-4)y#

#13x - 4y#

#(5x+3y)+(8x-7y)=13x-4y#

#(5x+3y)+(8x-7y)=5x+3y+8x-7y#
#=(5x+8x)+(3y-7y)=13x+(-4y)#
#(5x+3y)+(8x-7y)=13x-4y#
