Question

How do you solve `2h = 3h - 9`?

Answer 1

See a solution process below:

Explanation:

Subtract `color(red)(2h)` and add `color(blue)(9)` to each side of the equation to solve for `h` while keeping the equation balanced:

`2h - color(red)(2h) + color(blue)(9) = 3h - color(red)(2h) - 9 + color(blue)(9)`

`0 + 9 = (3 - color(red)(2))h - 0`

`9 = 1h`

`9 = h`

`h = 9`
