Arrange the equations in the correct sequence to find the inverse of f(x)=y=x-4/33-x ?
equations: (only 6 out of the 9 equations are used)
1) 33x - xy = y - 4
2) 33x + 4 = y(1 + x)
3) 33x - xy = y + 4
4) 33x + 4 = y + xy
5) y = f^-1(x) = 1+x / 33x+4
6) 33x - xy = y+4
7) x = y-4 / 33-y
8) y = f^-1(x) = 33x+4 / 1+x
9) x(33 - y) = y-4
