We need to find the value of k at which the equation 4(80+n)=(3k)n has no solution. Let's solve the above equation for n. So,
By using the distributing property.
Subtract 4n from each sides.
Take out n as a common factor Divide each sides by 3k-4.
So, Denominator of a rational equation cannot be 0 because if it will be 0 then the equation will be undefined and there will be no solution. Here the denominator is 3k-4. Let's set up 3k-4=0 to get the answer. So,
