Question

Find the inverse 2x+6/5

Answer 1

ANSWER

$\frac{5x - 6}{2}$

EXPLANATION

The given function is

$\frac{2x + 6}{5}$

Let

$y = \frac{2x + 6}{5}$

Interchange x and y.

$x= \frac{2y + 6}{5}$

Solve for y.

5x=2y+6

5x-6=2y

Divide both sides by 2

$\frac{5x - 6}{2} = y$

Hence the given function has inverse

$\frac{5x - 6}{2}$
