Equation 1) -2x-y=-9
Equation 2) 5x-2y=18
Multiply all of equation 1 by 2, so that both equations have (2y) in them.
1) 2(-2x-y=-9)
Simplify.
1) -4x-2y=-18
2) 5x-2y=18
Subtract equations with each other.
-9x=-36
Divide both sides by -9.
x=4
Plug in 4 for (x) into equation 1.
-2x-y=-9
-2(4)-y=-9
Simplify.
-8-y=-9
Add 8 to both sides.
-y=-1
Divide both sides by -1.
y=1
(4, 1)

Answer:
y = 2.4
Step-by-step explanation:
If y varies inversely as x, it means there's an inverse relationship between y and x, that is if x is increasing, y is decreasing and vice versa. In such instance, we have to find the constant of proportionality "k"
Hence,
y~1/x
y=k/x
When y =-6 and x =-2, we insert these values to find the value of the constant "k"
-6 = k/-2
k = 12.
Using this value of k to determine value of y when x =5 becomes:
y = 12/5
y = 2.4
10 birds each have 5 eggs. How many eggs do they have all together?
10*5=50eggs all together.
