    so you have 1/ f(2) = 8 let it there now, 2/ f−1(3) when f(x)=2x−73 you have to find f−1(x) which is 3x+72 and then f−1(3)=8 So, 1/ = 2 2/ = 8 now, 3/ solve for y : 2y+14 = 4y -2 16 = 2y y = 8 Summary : 1/ = 2 2/ = 8 3/ =8 conclusion: 2/ and 3/ have the same solution. Read it carefully, hopefully you can follow and know how to work on this kind of problem from now on. Good luck

    oh, mistake, f(2 ) =8 , they are all equal. I am sorry.
