Question

From sum of 3x-2xy+4y and x +3xy-11y. Subtract the sum of x +2xy-y and 3x -5xy+7y

Answer 1

Answer:

2хy₊9y

Step-by-step explanation:

3x-2xy+4y and x+3xy-3xy-11y

group like terms

3x+x=4x

-2xy+3xy+5xy

4y-11y=15y

so this is the answer for the first question.

2xy-y and 3x-5xy+7y

this one to you group like terms

x+3x=4x

2xy-5xy=-3xy

-y+7y=6y

so now you subtract

4x+5xy+15y

⁻

4x+3xy+6y=

2xy=9y
