kropot72 · Answer

If you add the two equations it will eliminate y and enable you to confirm the value of x.

-.- lol that's how you call me? lol...yes as @kropot72 said...you add the 2 equations and then you have 2x = 8

so yes x = 4

anonymous · Answer

$$x=6-y$$ then change the value of x in the second equation to get$$(6-y)-y=2$$rearrange to get$$2y=4$$therefore$$y=2$$put this value into one of the equations to get$$x+(2)=6      $$$$x=4$$
