Given the system of equations :

8x + 16y = 15 โ†’(1)

x = 5 - 2y โ†’(2)

By substitution with x from equation (2) at the equation (1) :


8(5-2y)+16y=15

Solve for y :


\begin{gathered} 8\cdot5-8\cdot2y+16y=15 \\ 40-16y+16y=15 \\ 40=15 \end{gathered}

The last result is un logic , which mean the given system of equation represents two lines with the same slope and different y- intercepts

So, the given system represents a parallel lines

So, the answer is option C. the solution set is the empty set
