-------------------------------------------------------------------------
Let x be the first number. The second number thrice the first, and the third is 5 less than twice the second.
------------------------------------------------------------------------ 
FIRST        x
SECOND      3x
THIRD       2*3x-5


Sum of them is S.
S=x%2B3x%2B6x-5
S=10x-5
highlight%28S%28x%29=10x-5%29
