N=25k+8=28m+22  with k=2n  25n+4=14m+11  25n−14m=7  with n=7h  25h−2m=1  h=−2i+1  m=25i+12  N=28(25i+12)+22=700i+358  there are 358 sweets, or 1058 sweets  ...
$${N}=\mathrm{25}{k}+\mathrm{8}=\mathrm{28}{m}+\mathrm{22} \\ $$$${with}\:{k}=\mathrm{2}{n} \\ $$$$\mathrm{25}{n}+\mathrm{4}=\mathrm{14}{m}+\mathrm{11} \\ $$$$\mathrm{25}{n}−\mathrm{14}{m}=\mathrm{7} \\ $$$${with}\:{n}=\mathrm{7}{h} \\ $$$$\mathrm{25}{h}−\mathrm{2}{m}=\mathrm{1} \\ $$$${h}=−\mathrm{2}{i}+\mathrm{1} \\ $$$${m}=\mathrm{25}{i}+\mathrm{12} \\ $$$${N}=\mathrm{28}\left(\mathrm{25}{i}+\mathrm{12}\right)+\mathrm{22}=\mathrm{700}{i}+\mathrm{358} \\ $$$${there}\:{are}\:\mathrm{358}\:{sweets},\:{or}\:\mathrm{1058}\:{sweets} \\ $$$$… \\ $$
