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 ?

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?

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)

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?

chihiroasleafBest ResponseYou've already chosen the best response.0
okay.., x  6 = z, so x = z + 6, do you get it so far?

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?
