-4x + (-6) = -x next you take the -4x and you would add it to the right side to get
-6 = 3x
lastly you divide -6 / 3 to get
x = -2

The balloon has a volume
dependent on its radius
:

Differentiating with respect to time
gives

If the volume is increasing at a rate of 10 cubic m/s, then at the moment the radius is 3 m, it is increasing at a rate of

The surface area of the balloon is

and differentiating gives

so that at the moment the radius is 3 m, its area is increasing at a rate of
