What is 3 = -2v − v

v=

-1 =v

Step-by-step explanation:

3 = -2v − v

Combine like terms

3 = -3v

Divide each side by -3

3/-3 = -3v/-3

-1 =v

First combine like terms on the right side.

The v terms can be combined to get -3v.

So we have 3 = -3v.

Now divide both sides by -3 to get -1 = v.

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is
