First, write the equations in slope intercept form:

y=mx+b

where:

m = slope

b= y-intercept

-3x-9y=18

4x+3y= 12

-9y=18+3x

y= (3x+18)/-9

y= -1/3x-2

4x+3y=12

3y= 12-4x

y= (-4x+12)/3

y= -4/3+4

system:

y= 1/3x-2

y= -4/3+4

Graph both equations:

Where the 2 lines cross each other is the solution:

x=6

y=-4
