Question

A. ( 3, -1)
B. ( 3, 1)
C. ( -3, 1)
D. ( -3, -1)

Answer 1

Answer:

B. (3, 1)

Step-by-step explanation:

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

x+y=4-------(2)

from (2)

x=4-y

now put value of x in equation (1)

2(4-y)-y=5

8-2y-y=5

8-3y=5

8-5=3y

3=3y

1=y

put value of y in equation (2)

then, x+1=4

x=3
