A. (-4, 5)
B. (8, 1)
C. (3, -2)
D. No solution
E. Infinite number of solutions

Answer 1

Answer: C

Explanation:

x + y = 1 , so x = 1- y. If you substitute this into the other equation you get:

3*(1 -y) -5y = 19

3 - 3y -5y = 19

-8y = 19-3

-8y = 16

-y = 16/8

-y = 2

y = 2 , now you can substitute y =2 into x = 1-y to get x:

x = 1 - (-2) =1+2= 3 , x =3

So the final answer is : (3,-2)
