<PRE><B>Question 235913</B>
Equation 1: {{{X + (X+2) + (X+4) + (X+6)}}} The 4 integers in term of the smallest one.  We increase each number by two because you only want the odd numbers.
Equation 2:{{{X = (X+4) + (X+6) - 25}}} combine like terms
{{{X = 2X - 15}}} Subtract X from both sides
{{{0 = X - 15}}} Add 15 to both sides
{{{15 = X}}}
Now plug 15 in for X into equation 1 to get the 4 numbers
Equation 1: {{{X + (X+2) + (X+4) + (X+6)}}}
{{{15 + (15+2) + (15+4) + (15+6)}}} Simplify
{{{15 + 17 + 19 + 21}}}

-------------------
19 + 21 = 40
40 - 25 = 15
