Answer:
There is no whole number answer.
Step-by-step explanation:
The solution to the equation is x = 1.62
<h3>How to solve the equation?</h3>
The equation is given as:

Next, we split the equations as follows:
y = x

Next, we graph the equations (see attachment)
From the attached graph, the equations intersect at
(x, y)= (1.62, 1.62)
Remove the y value
x = 1.62
Hence, the solution to the equation is x = 1.62
