Find an expression which represents the difference when (-2x+10y) is subtracted from (5x−7y) in simplest terms.
Zepler [3.9K]

Answer:

7x-17y

Step-by-step explanation:

We need to find the expression which represents the difference when (-2x+10y) is subtracted from (5x−7y) . Let the result is R.

So,

R = (5x−7y)-(-2x+10y)

Solving brackets as follows :

R = (5x−7y)+2x-10y

taking like terms together

R = (5x+2x)+(-7y-10y)

R = 7x-17y

Hence, when (-2x+10y) is subtracted from (5x−7y) the result is (7x-17y).
