6xy=12x
y=12x%2F6x
y=cross%2812%292cross%28x%29%2Fcross%286%29cross%28x%29
y=2.........a line parallel to x-axis
so, for x=1 or any other value of x we have y=2
+graph%28500%2C500%2C+-10%2C+10%2C+-10%2C+10%2C2%29+
4x%2B3y=0
3y=0-4x
3y=-4x
y=-%284%2F3%29x
if x=-3 then y=-%284%2F3%29%28-3%29....->...y=12%2F3....->...y=4

6xy=12x; x=1
y=12x/6x
y=2
6*1*2=12*1
12=12
------------------
4x+3y=0; x=-3
3y=-4x
y=-4x/3
y=-4*-3/3
y=12/3
y=4
4*-3+3*4=0
12-12=0
0=0
