-3x+13=16
Move +13 to the other side. Sign changes from +13 to -13.
-3x+13-13=16-13
-3x=16-13
-3x=3
Divide by -3 for both sides.
-3/-3x=3/-3
Cross out -3 and -3, divide by -3, then becomes 1*1*x=x
x=-1
Answer: x=-1
Ml/cm^3 (same measurement) would be the best unit.
Reason.....
cm can be measured with a simple ruler. Once you have area of the tank (length x width), it can be multiplied by the height to give you the unit it cm^3.
Water is measured in ml, which would make it easy to get the right amount because you now know the capacity!
Hopefully this helps :)
