Verified answer

f(x) = (x+1) / (x-3)

... y = (x+1) / (x-3)

or y (x-3) = (x+1)

or xy-3y = x+1

or xy-x = 3y+1

or x (y-1) = 3y+1

or x = (3y+1)/(y-1)

... f‾¹(x) = (3x+1)/(x-1)

easier thank you to unravel: 3/2(3x + 5) = -24 Multiply each and every thing by skill of two to cancel off the denominator: 3(3x + 5) = -40 8 enhance the brackets: 9x + 15 = -40 8 Subtract 15 from the two components: 9x = -sixty 3 Divide the two components by skill of 9: x = -7 ———————— to respond to your preliminary question: 2/3 x -24/a million = -40 8/3 = -sixteen

Write y = (x+1)/(x-3). Assuming y is known, solve for x.
