{Y= 3x
Yx=4
So far I have done this. Please tell me the next steps. Thank you.
X=Y4
Y=3(4Y)
Y=123Y

from
x = y4 , sub in y=3x
x = 3x  4
x  3x= 4
2x = 4
divide both sides by 2
x = 2
sub into y=3x
y = 3(2) = 6
x = 2, y = 6
your second last line
Y=3(4Y)
should have said:
Y = 3(y4)
then
y = 3y  12
2y = 12
y = 6, just like I had mine 
y = 3 x
y  x = 4
3 x  x = 4
2x = 4 Divide both sides by 2
x = 4 / 2 = 2
y = 3 x
y = 3 * 2 = 6
