Question 1058520
which are the intersection points of
2x -y =3 
If x = 0, y = -3
If y = 0, x = 3/2
Plot (0,-3) and (3/2,0) and draw a line thru them.
-----------
 x + y=6
If x = 0, y = 6
If y = 0, x = 6
Plot (0,6) and (6,0) and draw a line thru them.
----
Find the intersection::
y = 2x-3
y = 6-x
----
2x-3 = 6-x
3x = 9
x = 3, y = 3
------

b) x +3y = 18 ; 2x+ y = 11
y = (-1/3)x + 6
y = -2x+11
----
Solve for "x"::
(-1/3)x + 6 = -2x+11
(5/3)x = 5
x = 3 ; then y = -2x+11 = 5
