The first courier service cost is;


5x+14

Where, x is the number of kilograms delivered;

The second courier service cost is;


4x+15

Equating it, we have;


\begin{gathered} 5x+14=4x+15 \\ x=1 \end{gathered}

Thus, the weight that will result in equal cost is 1 kilogram.

And the cost is 5( 1 )+14 = $19
