Solve the system of equations and choose the correct answer from the list of options.
D + e = 12
-d + e = -8
Label the ordered pair as (d, e).
(0, 0)
(2, 10)
(12, 0)
(10, 2)
To solve the system of equations, we can add the two equations together to eliminate d:
D + e = 12
-d + e = -8
--------------
2e = 4
e = 2
Now, substitute e = 2 back into one of the original equations to solve for d:
d + a 2 = 12
d = 10
Therefore, the ordered pair is (10, 2), which corresponds to the option (10, 2).
