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 pairs as (d,e)
1) (0,0)
2) (3, -2)
3) (-2, 3)
4) (-3, 0)

Answer 1

2) (3, -2)

Explanation:

d + e = 1

- d + e = - 5

__________+

0 +2e = -4

e = -4/2 = -2

d = 1-(-2) = 3

so, (d, e) => (3, -2)
