<PRE><B>Question 1188041</B>
x, y, z, how many in first, second, third places
{{{x+y+z=24}}}


3 points for each of x
2 points for each y
1 point for each z


{{{3x+2y+z=53}}}


There were as many first-place finishers as second-place and third-place finishers combined.
{{{x-y-z=0}}}.


These two equations 
{{{system(x+y+z=24,and,x-y-z=0)}}}
means that {{{highlight(x=12)}}} and {{{y+z=12}}}


Here is a system of two equations in two variables.
{{{system(3*12+2y+z=53,y+z=12)}}}

.
