Subtract :(x – y) from (4y – 5x)

1.	Subtract :(x – y) from (4y – 5x)
Answer» (x – y) from (4y – 5x) The difference of two like terms is a like term whose coefficient is the difference of the numerical coefficient of the two like terms. We have, = (4y – 5x) – (x – y) Change the sign of each term of the expression to be subtracted and then add. = 4y – 5x – x + y = (-5x – x) + (4y – y) = -5x + 3y) = 3y – 5x

Answer»

(x – y) from (4y – 5x)

The difference of two like terms is a like term whose coefficient is the difference of the numerical coefficient of the two like terms.

We have,

= (4y – 5x) – (x – y)

Change the sign of each term of the expression to be subtracted and then add.

= 4y – 5x – x + y

= (-5x – x) + (4y – y)

= -5x + 3y)

= 3y – 5x
