Question

X-3=14 use the opposite operation found in the equation.

Answer 1

The volume can be determine by subtracting volume of smaller cuboid from the volume of the bigger cuboid.
Thus, by removing smaller cuboid from the bigger, we can determine the volume of the resultant figure.
Thus, Option (b) is correct.

Answer 2

Explanation:

x-3=14

x=14+3

x=17

verification

x(17)-3=14

17-3=14

14=14
