Numerical Answers Expected!

Answer for Blank 1:
----------------

Answer 1

y=-5

Answer 2

x=11

Answer 3

x=1

Answer 4

3x+-5=-2
3x=3
x=1

Answer 5

1 - 5 doesn't equal 6 though

Answer 6

That is if you do the other equation.

Answer 7

I would solve for x with the first equation, then use that to solve for y in the second, then check by inputting values.

3x+y=-2
x-y=6
x=6+y

Answer 8

thanks

Answer 9

then...

3(6+y)+y=-2
18+3y+y=-2
18+4y=-2
4y=-20
y=-5

Answer 10

You see?

Answer 11

Yes. So y=-5 is the answer?

Answer 12

No now 3x+-5=-2
3x=3
x=1. x=1is the answer

Answer 13

Alrighty! Thanks.

Answer 14

No problem
