Question

Solve the system of equations and choose the correct answer from the list of options.

d + e = 1
−d + e = −5
Label the ordered pair as (d, e).

(0, 0) (3, −2) (−2, 3) (−3, 0)

Answer 1

(-2,3) wouldn't work with the second equation (2+3=5 not -5) so it's out. (0,0) is obviously out 0+0=0 same with (-3,0) -3+0=-3. The only one left is (3,-2) 3-2=1 and -3-2=-5. Since it's the only one to fit it's the correct option :)

Answer 2

(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.
