To determine if a given value is a solution of the equation, we will substitute the given value in for the variable it has been assigned to.
In this equation, our variable is k.
[tex]25 = \frac{k}{5} ; k = 5[/tex]
Substitute 5 in for k:
[tex]25 = \frac{5}{5} [/tex]
Now we will simplify the right side of the equation:
[tex] \frac{5}{5} = 1[/tex]
25 = 1
25 does not equal 1, so we know that the given value 5 is not a solution for the equation.
