Answer 1

Answer:

d = 3h - 6

Step-by-step explanation:

Given formula:

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

Subtract 2 from both sides:

$\implies h-2=\dfrac{d}{3}+2-2$

$\implies h-2=\dfrac{d}{3}$

Multiply both sides by 3:

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

$\implies 3(h-2)=d$

Apply the distributive law  $a(b-c)=ab-ac$

$\implies 3h-6=d$

$\implies d=3h-6$

Answer 2

Answer:

$d=3h-6$

Step-by-step explanation:

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

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

                 -$2$

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

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

$3(h-2)=d$

$3h-6=d$

$d=3h-6$
