Answer 3

You can use the substitution method.

Answer 4

ok??? is that like put in a a number for x and y

Answer 5

Subtract 'y' to both sides in the first equation.

Answer 6

ok

Answer 7

Tell me what you come up with.

Answer 8

so x= 5-y

Answer 9

or x =y-5

Answer 10

Yep!

Now plug in '5 - y' for 'x' in the 2nd equation and solve for 'y'.

Answer 11

5 - y and y - 5 aren't the same.

Answer 12

Your x=5-y is fine. Now, what are you going to do with this? Hint: substitution method.

Answer 13

Can you plug in '5 - y' for 'x' in the 2nd equation and solve for 'y'?

Answer 14

im sorrry this makes o sense to me... lol

Answer 15

Okay, we have:

x = 5 - y
for the first equation

Our second equation is:

x - 2y = 2

Now in the first equation, x is equal to 5 - y, so we can plug that in for 'x' in the second equation.

5 - y - 2y = 2

Now solve that for 'y', can you do that?

Answer 16

3y =-3 so y = -1

Answer 17

right

Answer 18

???

Answer 19

x=4 and y=1

Answer 20

You have to combine like terms in 5 - y - 2y = 2.
So it would actually be 5 - 3y = 2

Answer 21

And then subtract 5 from both sides and divide by -1.
