make c the subject of the formula. w=ac/a-c

Starting with:

w = ac / (a - c)

Multiplying both sides by (a - c):

w(a - c) = ac

Expanding the left side:

wa - wc = ac

Rearranging:

wa = ac + wc

Factoring out c on the right side:

wa = c(a + w)

Dividing both sides by (a + w):

c = wa / (a + w)

Therefore, c is equal to wa divided by the sum of a and w.

To make c the subject of the formula w = ac / (a - c), we need to isolate the variable c on one side of the equation.

1. Start by multiplying both sides of the equation by (a - c) to remove the denominator:

w(a - c) = ac

2. Expand the equation by distributing w:

wa - wc = ac

3. Move the term wc to the other side of the equation:

wa = ac + wc

4. Factor out the variable c on the right side of the equation:

wa = c(a + w)

5. Divide both sides of the equation by (a + w):

c = wa / (a + w)

Therefore, c is the subject of the formula and can be expressed as c = wa / (a + w).
