Question

Solve the linear system of equations
2x-3y=2
x=y-2

Answer 1

Is ubstitution oka or am I thinking of the wrong thing?

Answer 2

*substitution okay

Answer 3

No its no substitution.

Answer 4

Not sure what you mean then. Are you trying to find hat x and y equal?

Answer 5

yes I'm trying to find x and y

Answer 6

Okay, so what's wrong with...
2x-3y=2 x=y-2
2(y-2)-3y=2
2y-4-3y=2
-y=6
y=-6

Answer 7

Then for x...
x=y-2
x=-6-2
x=-8

Answer 8

There are other methods she could use, I suppose. But I mean without her telling us what those methods are that she's using, we can't do much for her.

Answer 9

True. I figured substitution would be the easiest one because we already had x=y-2. That and i couldn't remember the names of the others. :P
