y= 2x / 3x-3
y(3x-3)= 2x
3xy -3y = 2x
3xy -2x= 3y
x(3y+2)=3y
x= 3y / 3y+2
f-¹(x) = 3x / 3x+2
B. f(x) = 3x+5 / x-4
y=3x+5 / x-4
y(x-4)=3x+5
yx-4y = 3x+5
yx-3x= 4y+5
x(y-3)= 4y+5
x= 4y+5 / y-3
f-¹(x) = 4x+5 / x-3
C. f(x) = 5-2x / x
y = 5-2x / x
yx = 5-2x
yx+2x = 5
x(y+2)=5
x = 5 / y+2
f-¹(x) = 5 / x+2
