Question 939838
Three numbers: a, b, c
:
We have three unknowns and only 2 equations here, the solution will be an expression
:
Write an equation for each statement
:
Sum of 3 numbers is 65.
a + b + c = 65
If one of the number is 24 less than the other number.
a = b - 24
In the first equation, replace a with b-24
(b-24) + b + c = 65
2b + c = 65 + 24
2b + c = 89
What is the 3rd number?
c = -2b + 89
