Question

Make k the subject of the formula h(k+6)=3h-k

Answer 1

k = -
`(3h)/(h+1)`

Explanation:

Given

h(k + 6) = 3h - k ← distribute parenthesis on left side

hk + 6h = 3h - k ( add k to both sides )

hk + k + 6h = 3h ( subtract 6h from both sides )

hk + k = - 3h ← factor out k from each term on the left side

k(h + 1) = - 3h ( divide both sides by (h + 1) )

k = -
`(3h)/(h+1)`
