Answer:
y= -2
x = 5
Step-by-step explanation:
Multiply the top equation by 2 to get
2x + 6y = -2
then subtract the bottom equation by the new equation to get
2x + 6y = -2
--------------------
2x + 2y = 6
which is
4y = -8
y = -2
If y = -2
Then plug -2 into y in the top equation to get x + 3(-2) = -1 and simplify which is
x + (-6) and add 6 to both sides to get x = -1 + 6
which is x = 5
K = 10
I think. I’m not positive sure though. Hope this helped!

Answer:
8 3/4 below sea level
Step-by-step explanation:
Given that:
Depth of fish at 7:00 A. M = 3 1/2 feets below sea level
Depth at 11:00a.m (4 hours later) = 5 1/4 feets below it's position at 7:00 a. M
Rational number to represent position of fish with respect to the water surface at 11:00 a. M
Position at 11:00 a. M :
Addition of the two depth distances given :
(3 1/2 + 5 1/4)
7/2 + 21/4 = (14 + 21) / 4 = 35 / 4
35/4 = 8 3/4 feets below sea level
