To solve the system of equations:
d + e = 12
−d + e = −8
Add the two equations together:
2e = 4
e = 2
Substitute e = 2 back into the first equation to solve for d:
d + 2 = 12
d = 10
Therefore, the ordered pair is (10, 2).
So the correct answer is (10, 2).
(10, 2)
Solve the system of equations and choose the correct answer from the list of options.
