Question

Solve the system of equations and choose the correct answer from the list of options. d + e = 15 −d + e = −5 Label the ordered pair as (d, e). (4 points) Question 3 options: 1) (0, 0) 2) (10, −5) 3) (5, 10) 4) (10, 5)

Answer 1

3) (5, 10)

Explanation:

d + e = 15

-d + e = -5

e = -5 + d

substitude e for -5 + d

d + -5 + d = 15

2d = 10

d = 5

figure out e

5 + e = 15

e = 10
