Answer:

x=1, y=−4

Explanation:

Divide each term by −2 and simplify.

x=−7y/2−13

7x+5y=−13

Replace all occurrences of x with −7y/2−13 in each equation.

−39y/2−91=−13

x=−7y/2−13

Solve for y in the first equation.

y=−4

x=−7y/2−13

Replace all occurrences of y with −4 in each equation.

x=1

y=−4
