anonymous · Answer

multiply the first one by (-2) and get:
-2x+4y=-6

anonymous · Answer

right

anonymous · Answer

then, add the other one to it:
-2x+4y=-6
  2x-3y = 9
----------
  0x+y = 3

@SwoleNationIzBack!!  seriously what you say isnt gonna hurt me. so please leave me alone cause i have done nothing to you

b is correct?

anonymous · Answer

ya

anonymous · Answer

just put each of them in the equations

anonymous · Answer

sure, we got this result from addition:
-2x    +4y =-6
 2x     -3y =  9 
-------------
0x+       y =  3

well, it states y=3. and you can put that in any equation to also get x!
x-2y=3
x-2(3)=3
x-6=3
x = 9
