Question

In the below system, solve for y in the first equation.
2x + y = 11
5x - 2y = -1
CHOICES:
2x + 11
-2x + 11
2x - 11
-2x - 11
PLEASE HELP!

Answer 1

\[2x - 2x + y = 11 - 2x\]

Answer 2

For 2x + y = 11?

Answer 3

I am lost lol

Answer 4

That was a hint. You want to get y by itself. You do that by doing the same thing to both sides of the =.

Answer 5

So then 5x -5x - 2y = -1-5x?

Answer 6

So we can get y by itself on the left side by subtracting 2x. But that means we have to subtract 2x from the right side also. Then you can just simplify it.

Answer 7

Right.

Answer 8

Ok, then after that?

Answer 9

If you solve this, There will be some hope. I need an example to study!

Answer 10

Well, for the first one, we're basically done. Just cancel the x's.

Answer 11

The second one ends up \(\frac{-2y}{-2} = \frac{-1 - 5x}{-2}\)
You'll have to simplify that. Be careful with the negative signs.

Answer 12

so, the answer choice would be 2x-11?

Answer 13

No, that isn't what it says. 11 - 2x.

Answer 14

oh, -2x + 11?

Answer 15

Right

Answer 16

Thanks!!!!!
