Question

The sum of three numbers is . The second number is times the third. The third number is less than the first . What are the numbers?

Answer 1

I think your question is not complete.. :)

Answer 2

oops! sorry haha here

The sum of three numbers is 96 . The second number is3 times the third. The third number is 6 less than the first . What are the numbers?

Answer 3

let the three numbers are x,y,z

from the first sentence,
"The sum of three numbers is 96"
how do you say this in x,y,z ?

Answer 4

not sure i understand what you mean by how we say this in x,y,z

Answer 5

let's say that the three numbers are x,y, and z.
the first sentence say that "The sum of three numbers is 96" ,
we can write the sentence as "x+y+z = 96"
it's what I mean.. :)
do you understand now?

Answer 6

oh ok yesss sorry haha so x,y, and z would be 32 bcause 96/3 =32

Answer 7

wait..., we have no information that x, y, and z are equals...

from the second sentence, we have " The second number is3 times the third"
if y is the second number, and z is the third number, how do you write this in math? (in y and z)

Answer 8

3z=y ?

Answer 9

correct... :)

now, from the third sentence, we have " The third number is 6 less than the first "
let, x be the first number and z be the third number, how do you write it in term of x and z?

Answer 10

x-6=z

Answer 11

okay.., x - 6 = z, so x = z + 6,
do you get it so far?

Answer 12

now, we have three equations

x+y+z = 96
3z = y
x = z + 6

now, substitute (change) the value of x and y in the first equation with the second and third equation, what do you get?

Answer 13

yes =) however i feel like that was the easy part.. and the hard part is coming =o
