Arrange the equations in the correct sequence to find the inverse of f(x) =y = 3x/8+x
these must be in correct order!
titles
x(8 + y) = 3y
y=f^-1(x) = (3-x)/8x
8x=3y-xy
8x=y(3-x)
8x=y(x-3)
x= 3y/8+y
y=f^-(x) = 8x/3-x
8x+xy = 3y

Ответ:
Also, don't use lower case and upper case interchangeably.
In algebra, x and X are different, as are y and Y.
f(x) = y = 3x/(8+x)
Switch x and y, solve for y:
x = 3y/(8+y)
x(8+y) = 3y
8x+xy = 3y
8x = 3y−xy
8x = y(3−x)
y = f⁻¹(x) = 8x/(3−x)
I hope this helps, love
