Answer:

x=2

Step-by-step explanation:

-2x + 4 = 6x - 12

First add 2x to each side: 4=6x−12+2x

Now simplify 6x-12+2x: 4=8x-12

add 12 to both sides: 4+12=8x

Simplify 4+12: 16=8x

Divide both sides by 8: 16/8

you end up with x=2

Hope this helps :)

h is the height

so the volume is :

V = 4*12*3.5
V=168 m³

Multiply by 2/3 to get the volume of the water

V' = 168*(2/3)
V' = 112 m³
