X+3y=5

4x+4y=4 I tried to work this problem and

this is what I came up with.

x+3y=5

x+4y=20

7y=15

y=7/15

and x= (5+y)/4

(5+7/15)/2

2/15

x=2/15

x=2/15, y=7/15 I would like for someone to check to see if it is correct.

**mahesh**, Monday, July 15, 2013 at 3:06amPlease see your third line: It should be

4y-3y=20-5 or y=15, by subtracting first equation from second.

Now x+3*15=5

Or x=5-45=-40. Check:-40+4*15=20 by putting values in second equation.

This -40=15-60=-40 OK.
