Answer:
Option B) The variable Y will cancel out first.
Step-by-step explanation:
we have
5x-y=-21 ----> equation A
x+y=-3 ----> equation B
Solve by elimination
Adds equation A and equation B
5x-y=-21
x+y=-3
--------------
5x+x=-21-3 ----->variable y will be eliminated first
6x=-24
x=-4
Y=x^2
substitute the values into the original equation
0=4^2
0=16
No it does not satisfy the equation because 0 does not equal to 16
