Question

3x=4(c-d)/d make d the subject

Answer 1

Answer:

$d = \frac{4c}{3x + 4}$

Step-by-step explanation:

$3x = \frac{4(c - d)}{d}$

Multiply both sides by d:

$3xd = 4(c - d)$

Expand:

$3xd = 4c \: - 4d$

+4d on both sides:

$3xd + 4d = 4c$

Factorise d out of the left-hand side:

$d(3x + 4) = 4c$

Divide both sides by (3x +4):

$d = \frac{4c}{3x + 4}$
