Question

How do you solve `-2(h-1)-3(h+4)=0`?

Answer 1

To make life easier, I would first multiply everything by `-1`

Explanation:

`->+2(h-1)+3(h+4)=0`

Expand the brackets:
`->2h-2+3h+12=0`

Unknown to the left, numbers to the right:
(reverse signs when crossing over)

`->2h+3h=+2-12->5h=-10->h=-2`
