Q:
At the party, 3/5 of the girls had brown hair. If 12 girls did not have brown hair, how many girls were at the party?
-----------------------------------------------------------------------------
A:
Let x = number of girls at the party
x+=+%283%2F5%29x+%2B+12
x+-+%283%2F5%29x+=+12
%282%2F5%29x+=+12
x+=+12%285%2F2%29
x = highlight%2830%29
Answer: highlight%2830%29
