Question

What is the inverse of 3/x+7

Answer 1

\(\bf {\color{red}{ y}}=\cfrac{3}{{\color{blue}{ x}}+7}\qquad inverse\implies {\color{blue}{ x}}=\cfrac{3}{{\color{red}{ y}}+7}\)

solve for "y"

Answer 2

doesn't the inverse mean given what y = then find what x = ?
y = 3/(x + 7)
3/y = x + 7
x = 3/y -7
