Question

I need help, I know it gave me the answer but I don’t understand how it got (-3) someone explain please

Answer 1

Answer: h=14

Explanation:

If x=-18, then

h=17+(-18)/6

h=17+(-3)

h=17-3

h=14

Answer 2

Explanation:

so, the calculation was : h = 17 +
`(-18)/(6\\)`

To subtract "
`(-18)/(6)` " we need to make it the same denominator as "17"

(it's not written but technically 17 =
`(17)/(1)` )

Yet, we see that
`(-18)/(6) =(-3* 6)/(1*6)`

We just need to remove both the 6 that are not useful here and :

`(-3*6)/(1*6) =(-3)/(1)= -3`

We obtain h = 17 - 3 = 14

hope it helped :)
