Question

Solve the following system of equations: (1 point)

−2x + y = 1
−4x + y = −1

a
(3, 1)

b
(−1, 3)

c
(−1, −3)

d
(1, 3)

Answer 1

Answer:

-2x+y=1

-2(1)+3=1

-2+3=1

1=1

-4x+y= -1

-4(1)+(3)= -1

-4+3= -1

-1= -1

hence,d)1,3 is right answer.

hope it helps you

Answer 2

-4x+y=-1

y=-1+4x

1+y=4x

then i used common sense and plugged the given answers in.

1+(3)=4(1)

4=4

D. (1,3)
