3x+%2B+5y+=+29.......1
-
3x+%2B+2y+=+44........2...subtract 2 from 1
--------------------------
3x-3x%2B5y-2y=29-44
cross%283x-3x%29%2B5y-2y=29-44
5y-2y=29-44
3y=-15
y=-15%2F3
y=-5...now find x


3x+%2B+5%28-5%29+=+29.......1

3x+-25+=+29

3x+=+29%2B25

3x+=+54

x+=+54%2F3

x+=+18
check:


3%2A18+%2B+2%28-5%29+=+44........2

54+-10+=+44
44+=+44
