Answer:

6 is not a solution to the given equation.

Explanation:

We are given the equation
x^2-4=5x

We need to know whether or not x=6 is a solution. This means that we should substitute in 6 for each instance of x. Then, if both sides of the equation are equal, then 6 is a solution to the equation.

$x^2-4=5x\\\\(6)^2-4=5(6)\\\\36-4=30\\\\32=30$

As 32 ≠ 30, 6 is not a solution to the given equation.
