Answer:

x = 2

y = -3

Explanation:

y = -x - 1 and 5x - 2y = 16 replace y with -x-1 in the second equation

5x - 2(-x-1) = 16

5x + 2x + 2 = 16 add like terms

7x + 2 = 16 subtract 2 from both sides

7x = 14 divide both sides by 7

x = 2 now we can use this information to find y

y = -x-1 replace x with the value we found

y = -2-1

y = -3
