Question

Help Please!! <3
3 methods you can use to solve a system of equations are:
graphing
subsstitution
elimination

Solve each system by any method of your choice:

Answer 1

Elimination is a good method to use here. The equations are already set up nicely for that. If you add the left halves:

(x + x) + (y - y) = 6 + 12

From this point, you should be able to solve for "x" here.

Answer 2

Thanx! Would you add 6 and 12?

Answer 3

Yes, that would be the next step.

2x + 0 = 18

2x = 18

x = 9

Answer 4

Sorry that took so long. Openstudy hung up on me. @ell

Answer 5

Haha(: It is okay, thanks for helping!
So the two answers are 18 and 9 ??

Answer 6

And now, you can take that value for x and put it in either of the original equation to get "y".

9 + y = 6 -> y = -3

So x = 9 and y = -3

Answer 7

And that's it! You're done!

Answer 8

Thanx so much!! I really appreciate it! :) GBU!

Answer 9

uw!
