How do you simplify #(5x+3y) + (8x-7y)#?

Answer 1

Hazel Anglin

See a solution process below:

First, take every term out of parenthesis, paying close attention to the proper handling of each term's sign:

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

Next, terms that belong to groups:

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

Now, blend similar terms together:

#(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#

To simplify the expression (5x + 3y) + (8x - 7y), you combine like terms by adding the coefficients of the same variables:

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

= 13x - 4y

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
