Any to solve the inverse function of this problem, ?

see explanation

Step-by-step explanation:

(a)

let y = f(x), that is

5x + 3 = y

Rearrange making x the subject

Subtract 3 from both sides

5x = y - 3 ( divide both sides by 5 )

x = (y - 3) / 5, hence

(x) = (x - 3) / 5

(b)

(8) = (8 - 3) / 5 = 5/ 5 = 1

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
