Question

Solve the linear system using elimination.
Hello you guys. I just want to know how you flip it.
2x - y= -11
y = -2x -13

Answer 1

rewrite the second equation by adding 2x to both sides.

Answer 2

for the second equation \[y=-2x-13\] you already solved for y.
plug that y into the first equation, giving you\[2x-(-2x-13)=-11\]

Answer 3

Don't get it.

Answer 4

:p

Answer 5

So chrismoon, you are instructing the asker to ignore the directions which say to solve using elimination?????

Answer 6

ALl I just want to know is just how to flip it. and thats it.

Answer 7

@mariannu Do what I said and then add the two equations to eliminate y from the system

Answer 8

What do you mean by flip it?

Answer 9

So its y + 2x = -11???
