swap variables ...
multiply both sides by 8 ...
solve for y to finish it.
Hello - I need help with the following problem. I was asked to find the inverse of: f(x) = 7x+3 over 8
If I’m doing this correctly, I would first replace f(x) with “y”, then I switched “y” and “x”. I believe my next step would be to multiply both sides by 8, correct? So I think that would give me 8x = 56y+24? From here I’m stuck because I’m forgetting a process I’ve already learned. I know I need to get y by itself but how?
Your help is greatly appreciated.
