Answer:

C. (3, -2)

Step-by-step explanation:

x + y = 1 ➡ x = 1 - y we can use this information in the first equation to find the value of y

3x - 5y = 19 replace x with 1 - y

3 ×(1-y) - 5y = 19 ➡ 3 - 3y - 5y = 19 add like terms

-8y = 16

y = -2 if y is 2 then x is

x + y = 1 ➡ x +(-2) = 1 and x = 3
