You can put this solution on YOUR website!

3x+%2By+=+6..........eq.1
x+ y + 2 I guess you have x%2B+y+=+2..........eq.2
start with x%2B+y+=+2..........eq.2 and solve for x
x+=+2-y........substitute in eq.1
3%282-y%29+%2By+=+6..........eq.1 and solve for y
6-3y+%2By+=+6
6-2y+=+6
6-6+=+2y
0+=+2y
highlight%28y=0%29.....substitute in x+=+2-y

x+=+2-0
highlight%28x+=+2%29
so, intersection point for given lines is: (2,0)
