Drag each tile to the correct box. Not all tiles will be used.
Arrange the equations in the correct sequence to find the inverse of f(x) = y = 3x / 8 + x

Inverse of f(x)

Step-by-step explanation:

Explanation:-

Step(i):-

Given the function

Given function is one-one and onto function

Hence f(x) is bijection function

now cross multiplication, we get

            ( 8+x)y = 3 x

             8 y + x y = 3 x

             8 y = 3 x - x y

taking Common 'x' we get

            x (3 - y) = 8 y

Step(ii):-

The inverse function

The inverse function of x

Final answer:-

Inverse of f(x)

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
