Question

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

Answer 1

d = 3h - 6

Explanation:

`h = (d)/(3) + 2`

subtract 2 on all sides :

`(h) - 2 = ((d)/(3) + 2) - 2 \\ \\ h - 2 = (d)/(3)`

multiply 3 on all sides:

`(h - 2) * 3= (d)/(3) * 3 \\ \\ 3(h - 2) = d`

open bracket:

`d = 3h - 6`

Answer 2

d= 3h-6

Explanation:

h= d/3+2

h-2= d/3

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