Answer:
x=-2 and y=-3
Step-by-step explanation:
2x+4y=-16
-2(-2x+2y=-2)
2x+4y=-16
4x-4y=4
6x=-12
x=-2
2x+4y=-16
2(-2)+4y=-16
-4+4y=-16
+4 +4
4y=-12
y=-3

So your answer is 7!
You multiple everything in the ( )’s with the number outside of the ( )’s
T=time
when the piano dropped at t=0, its velocity also equals 0
