The inverse is found by interchanging x and y
f(x) = y

Multiply both sides by y + 1
x*(y + 1) = 2y - 3 Remove the brackets on the left
xy + x = 2y - 3 Subtract xy on both sides
x = 2y - xy - 3 Add 3 to both sides
x + 3 = 2y - xy Factor out y on the right. Use the inverse distributive law
x + 3 = y*(2 - x) Divide both sides by 2 - x
