Question 94751
Given:
.
{{{D=M/V}}}
.
To solve for V, begin by getting rid of the V in the denominator. You can do this by multiplying
both sides of the equation by V to get:
.
{{{D*V=(V*M)/V}}}
.
Note that on the right side the V multiplier is in the numerator and it cancels the V in
the denominator:
.
{{{D*V=(cross(V)*M)/cross(V) = M}}}
.
Next, get rid of the factor D on the left side by dividing both sides by D to get:
.
{{{(D*V)/D = M/D}}}
.
On the left side the D in the numerator cancels the D in the denominator:
.
{{{(cross(D)*V)/cross(D) = M/D}}}
.
As a result you are left with:
.
{{{V = M/D}}}
.
That's the answer you are looking for.  Once you get used to this form you will become familiar
with the rule that says given something of the form:
.
{{{A = B/C}}}
.
You can quickly solve for C by just reversing the positions of A and C to get:
.
{{{C = B/A}}}
.
Hope this helps ....
