Very easy.
Simply substitute the expression y = 5x - 17 of the first equation into the second equation, replacing "y".
You will get a single equation for "x":
8x + 6*(5x-17) = -14.
Simplify and solve it for "x".
Then restore "y" using the first equation.
This method is called the "substitution method".
