Question

If g+9=4 and h-8--3, what is the
value of g + h?

Answer 1

g + h = 6

Explanation:

We are told that:

•
`g + 9 = 4`

•
`h- 8=3`.

To calculate the value of g + h, we have to rearrange the above equations to make g and h their respective subjects:

•
`g + 9 = 4`

⇒
`g + 9 - 9 = 4 - 9` [Subtracting 9 from both sides]

⇒
`g = \bf -5`

•
`h- 8=3`

⇒
`h - 8 + 8 = 3 + 8` [Adding 8 to both sides]

⇒
`h = \bf 11`

Now that we know the values of g and h, we can find the value of g + h:

`g + h`

`= -5 + 11`

`= \bf 6`

Therefore the value of g + h is 6.
