You can put this solution on YOUR website!
x+3y=14
-x+y=2
***********************************
add the two equations
4y = 16
y = 4
now substitute for y in first equation
x + 12 = 14
x = 2
*************************************
check solution in second equation
-2+4 = 2
2 = 2
*************************************
solution x = 2, y = 4 checks
