Question 238580
Hello, 
Let's multiply the second equation by 10 so it will look like this:
 -2x   -10y= -12
(10)3x+(10)y=(10)4  Now we can add both equation (note: the y cancels out)
which leaves us with:
28x = 28
x = 1 Now plug 1 into either equation and you get 
y = 1
Plug these into the equations and it works out.
