3 similar chocolate bars and 4 similar packets of candy weigh 200 g. 3 such

\n" ); document.write( "chocolate bar?
\n" ); document.write( "
Let weight of a chocolate bar, and a packet of candy, be B, and C, respectively
\n" ); document.write( "Then we get: 3B + 4C = 200 ------ eq (i)
\n" ); document.write( "Also, 3B + 7C = 260 ------ eq (ii)
\n" ); document.write( "3C = 60 ------ Subtracting eq (i) from eq (ii)
\n" ); document.write( "Weight of a chocolate bar, or \"matrix%281%2C6%2C+C%2C+%22=%22%2C+60%2F3%2C+%22=%22%2C+20%2C+g%29%29\"
\n" ); document.write( "Substitute 20 for C in either eq (i) or eq (ii) and solve for B to get the weight of a chocolate bar.\r
