Question 202984
"One silver leaf is worth 14 copper leaves" ___ s = 14c


"one gold leaf is worth 71 copper leaves" ___ g = 71c


"she has 11 more copper leaves than silver leaves" ___ C = S + 11


"a total of 35 leaves" ___ C + S + G = 35


substituting ___ S + 11 + S + G = 35 ___ 2S + G = 24 ___ G = 24 - 2S


"her money is worth 572 copper leaves" ___ C + 14S + 71G = 572


substituting ___ S + 11 + 14S + 71 (24 - 2S) = 572 ___ 15S + 1704 - 142S = 561 ___ 1143 = 127S ___ 9 = S


substituting ___ G = 24 - 2(9) ___ G = 6


substituting ___ C = 9 + 11 ___ C = 20
