Answer:
14
Step-by-step explanation:
hi! so the question is asking what h is when you input -18 for x, right?

- let's see what the equation looks like now

- easy as that!
now let's do the math :)
- because of PEMDAS, remember to do the fraction (dividing) first!

we can change that to --> h = 17 - 3
h = 14
let me know if you're still confused!
