Question 108027
x-2y=8
3x-2y=12 

2y=(8-x)
2y=(12-3x)

y = (-1/2)x+4
Plot two points:
If x = 0, y = 4
If x= 2, y = 3
Plot (0,4) and (2,3)
Draw a line thru them.
------------------------

y = (-3/2)x+6 
Plot two points:
If x=0, y = 6
If x=2, y =3
Plot (0,6) and (2,3)
Draw a line thru them.
------------------------
{{{graph(400,300,-10,10,-10,10,(-1/2)x+4,(-3/2)x+6)}}}
--------------
Solution for the system: (2,3)
