Multiply one of the equation so that you can rule out either the #x# or the #y# value, then add them up to actually let one of them vanish.

Explanation:

Multiply the first equation by #2#, then add both equations up.

This gives: #-4x=6y=6#
Adding up: #1x-0y=3#, simplified: # x=3# since #0 times y =0#
