Question 229480
Sam has twice as much money as Mary, who has $175 less than Larry. But Larry has as much money as Sam and Mary have together. How much money does each person have?
<pre>
>>...Sam has twice as much money as Mary,...<< 

{{{S=2M}}}


>>...Mary, who has $175 less than Larry...<<

{{{M=L-175}}}

>>...Larry has as much money as Sam and Mary have together...<<

{{{L=S+M}}}

So the sytem of equations is

{{{system(S=2M,M=L-175,L=S+M)}}}

Can you solve this system? If not post again asking how.

Answer: Mary has $87.50, Larry has $262.50, and Sam has $175.
