Answer:
You MUST use parentheses around denominator 8+x, or ANY denominator that consist of more than a single number of variable.
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)
