You can put this solution on YOUR website!
h, Hundreds
t, Tens
u, Ones

system%28h=t%2F2%2Cu=t%2B1%2Ch%2Bt%2Bu=11%29

system%28h=t%2F2%2Cu=t%2B1%2Chighlight_green%28t%2F2%2Bt%2Bt%2B1=11%29%29

One equation in one variable, for first finding t.
t%2F2%2B2t=10
t%2B4t=20
highlight%28t=4%29-----------and you can continue to find all the rest and the number.
