Question 386786
At a party 1/4 of the people are children.  There is 1/2 as many men as women, 
and 15 more women than children.  If the total number of people is x, form an 
equation in x and solve.
...
total = x
...
children = x/4
...
women = x/4+15
..
Men= 1/2*(x/4  +15)
=x/8 +15/2
...
{{{x/4 +x/4 +15 +x/8 +15/2=x}}}
..
{{{x/4 +x/4 +x/8 -x =-15 -15/2}}}
...
LCD = 8
....
{{{(2x+2x+x-8x)/8=(-30-15)/2}}}
...
{{{-3x/8 =-45/2}}}
...
cross multiply
-6x=-360
/-6
x=60
...
Total 60
