x = 13.4 is our solution. enter image source here

We have

$sqrt(5*x+14) = 9$

Step 1

Square both sides of the equation.

$( 5*x + 14) = 81$

Step 2

$5*x = 67$

Step 3

$x = 13.4$

This is our required solution.

When we refer to the graph, we find that graph{sqrt(5*x + 14) = 9, has an intersection point (13.4, 9).
