x-2y=8
3x-2y=12 


first write the equation in terms of y

y = x-8/2

y = 3x-12/2

{{{ graph( 300, 200, -6, 5, -10, 10,  x/2-4 ,(3x)/2-6) }}} 


From the graph we can see that x = 2 and y = -3

Check :

x-2y=8

pluggin the value of x  = 2 and y = -3 in the above equation we have,


2 - 2(-3) = 8

2 +6 = 8

8 = 8 

LHS =RHS

Hence the solution
