Question

Which ordered pair (x, y) satisfies the system of equations?

x = y − 3
x/2 + 2y = 6

A) (−3, 0)

B) (0, 3)

C) (6, −3)

D) (36, −6)

Answer 1

(0,3)

Explanation:

Plug in the coordinates:

-3=0-3 -3=-3 Right

-3/2+2(0)=6 -1.5=6 Wrong

0=3-3 0=0 Right

0/2+2(3)=6 6=6 Right

6=-3-3 6=-6 Wrong

6/2+2(-3)=6 3+-6=6 3=6 Wrong

36=-6-3 36=-9 Wrong

36/2+2(-6)=6 18-12=6 6= 6 Right

Both have to say right
