Answer:
-2x-y-15
Step-by-step 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
