Answer:

x = -1

y = -9

Explanation:

Add each linear equation:

Sum: 5x = -5

Divide each side by 5:

Quotient: x = -1.

Substitute x = -1 into the first equation:

4(-1) - y = 5

Solve:

-4 - y = 5

Add 4 to both sides of the equation:

-y = 9

y = -9.

Check with the second equation:

-1 + -9 = -10.

Correct.
