6. y = 11 + 4x

3x + 2y = 0

Y=11+4x

Can be rearranged to:

y-4x=11

Then you put them on top of each other (like simultaneous equations):

y-4x=11

2y+3x=0

We have to make either the y or x in both equations be the same. So the easiest way would be to times the first equations by 2 to have both equations have 2y:

2y-8x=22

2y+3x=0

So then you take them away to make:

-11x=-22

You can remove the - as both side have - which makes:

11x=22

Then you just simplify to make

x=2

You put that back into one of the equations:

y=11 + (4x2)

y=11+8

y=19

So the answer is x=2 and y=19
