Question 685626
4x-5y=28
5x+6Y=14
 Step one, isolate a variable. I prefer to isolate y. 
 -5(4x -5y =28)
 4(5x +6y =14)

-20x +25y =-140
 20x +24y = 56
 The x's cancel out leaving you:
   49y= -84
then divide. y=-3
To figure out x, you do the same thing except you don't have to use a negative number because there is already one.
6(4x-5y=28)
5(5x+6Y=14)
24x -30y =168
25x +30y =70
29x=238
x= 4.85
I hope this helps. (:
