Question

Make d the subject of the formula h= d/3 + 2

Answer 1

Answer:

d = 3h - 6

Step-by-step explanation:

$h = \frac{d}{3} + 2$

subtract 2 on all sides :

$(h) - 2 = (\frac{d}{3} + 2) - 2 \\ \\ h - 2 = \frac{d}{3}$

multiply 3 on all sides:

$(h - 2) \times 3= \frac{d}{3} \times 3 \\ \\ 3(h - 2) = d$

open bracket:

$d = 3h - 6$

Answer 2

Answer:

d= 3h-6

Step-by-step explanation:

h= d/3+2

h-2= d/3

d= 3(h-2)= 3h-6
