You can put this solution on YOUR website!
c, how many small coins (cinco, chico)
g, how many large coins (grande)

system%28c%2Bg=45%2C5c%2B10g=340%29

highlight_green%28system%28c%2Bg=45%2Cc%2B2g=68%29%29

Subtract the first equation from the second equation to eliminate c and get the value for g. Use the found value of g to find the value of c.
