Question

Anyone know how to do this?

Answer 1

-2x-y-15

Explanation:

5x+3y+4-9x-8+2x-4y-11

you add the x together

5x+2x=7x

7x-9x=-2x

then yourewrite the problem

-2x+3y+4-8-4y-11

then you can solve for the y

3y-4y= -1y but you do not need to put the 1 since -y is the same as -1y

we can rewrite the problem again

-2x-y+4-8-11

4-8=-4

-4-11=-15

answer

-2x-y-15
