how'd you get that? i have to show my work. :)

anonymous · Answer

WHOA, that was wrong, let me re-do with work.

anonymous · Answer

thankyou <3

anonymous · Answer

Okay, I got the answer. 
x=7
y=-12
Now I'll show the working.

anonymous · Answer

Using the substitution method, rearrange the first equation to "x="
Add y to the other side and you get x=19+y
Now that we know what x is, plug it into the second equation for the x value.
2(19+y)+y=2
Solve as you would a normal problem.
38+2y+y=2
38+3y=2
3y=-36
y=-12.
Now plug in -12 for y in any other the two equations.
2x+(-12)=2
2x=14
x=7
or 
x-(-12)=19
x+12=19
x=7

thankyou so much :)

Got it? :)

anonymous · Answer

might be easier just to add them and get 
$$3x=21$$ so 
$$x=7$$
