The two equations given in the question are
x = y + 10
And
x = 2y + 3
Now let us substitute the value of x in the second equation with that of the first equation. We get
x = 2y + 3
y + 10 = 2y + 3
y - 2y = 3 - 10
- y = - 7
y = 7
Now putting the value of y in the first equation, we get
x = y + 10
= 7 + 10
= 17
So the value of x comes out to be 17 and the value of y comes out to be 7.

Answer:
New height = 6
Step-by-step explanation:
The water is going to be the same volume no matter how the tank is orientated.
So you can do this 2 ways.
First way
Find the volume in the tank when the water goes up 24 cm on the height.
V = L*W*h
L = 8
W = 10
H = 24
V = 1920 cm^3
Now do it using the
L = 40
W = 8
h = ?
1920 = L * W * h
1920 = 40 * 8 * h
1920 = 320 * h
h * 320 = 1920
h = 1920/320
h = 6
Or you can do it without finding the 1920
L*W*h = L1 * w1 * h1
8*10*24 = 40 * 8 * h The 8's cancel
10*24 = 40*h Divide both sides by 10
24 = 4h Divide by 4
h = 6
Same as you got before.
