Solve the system of equations below. x + y = -2
2x - y = 5

Answer choices

A. (2,-1)
B. (1,-3)
C. (9,0)

(1,-3)

Step-by-step explanation:

x+y=-2 equation(1)

x=-2-y

2x-y=5equation (2)

now ,

putting value of x in equation (2)

2x-y=5

2(-2-y)-y=5

-4-2y-y=5

-3y=5+4

-3y=9

y=-3

again,putting of value y in equation 1

x+y=-2

x-3=-2

x=-2+3

x=1
