Answer:
x = 12
y = -29
Step-by-step explanation:
Our given equations: x + y = -17 and x - y = 41
Solve for x and substitute.
x = -17 - y
(-17 - y) - y = 41
-17 - 2y = 41
2y = -58
y = -29
Solve for x using y
x + (-29) = -17
x = 12
Answer:
The answer is D
x = 4
y = -2
z = 3
Step-by-step explanation:
Plug in the values of x and z into the first equation, and see that D is the only choice that is correct.
I think B is the only polynomial because A and C both have roots that aren't supposed to be in polynomial expressions and you can't divide (D)
