>>...I could use your help. There are 24 spooks in the haunted house. The

number of scarecrows is equal to the number of witches plus 4. The number of

witches is equal to the number of ghosts minus 8. how many witches and ghosts

and scarecrows are there? Thanks

Let x = no. of witches 

Let y = no. of ghosts

Let z = no. of scarecrows

>>...There are 24 spooks in the haunted house...<<

Translation: x + y + z = 24

>>...The number of scarecrows is equal to the number of witches plus 4...<<

Translation: z = x + 4

>>...The number of witches is equal to the number of ghosts minus 8...<<

Translation: x = y - 8

So you have this system of three equations and three unknowns:

Can you solve it?  If not post again.

x + y + z = 24

z = x + 4

x = y - 8

Answer x=4 witches, y=12 ghosts, z=8 scarecrows
