Question 873405: a+b+c=118
I need to find 3 numbers that add up to 118. I have 48,28,40 and 42,36,40 but the three numbers also has to fit into this equation, 1a+2b+1c=135. I tried to find an answer for that but I couldn't find anything.

You can put this solution on YOUR website!
To find 3 numbers, you need three equations.
a%2Bb%2Bc=118
a%2B2b%2Bc=135
Subtract eq. 1 from eq. 2,
a%2B2b%2Bc-a-b-c=135-118
b=17
So that leaves you with
a%2Bc=101
So you can get one variable in terms of another.
c=101-a
Then your solution would look like,
(a,17,101-a) for any value a.
