To solve this system of equations, we'll solve the second equation for x and substitute it into the first equation:

From the second equation, we have:
2x = −17 + 7y
x = (−17 + 7y) / 2

Now substitute this expression for x in the first equation:
−5((−17 + 7y) / 2) − 8y = 17

Simplify the equation:
(85 - 35y) / 2 - 8y = 17
85 -...
