The first day, a contractor hired 11 carpenters, 3 masons, and 5 helpers.
\n" ); document.write( " The second day, he hired 6 carpenters, 5 masons, and 2 helpers.
\n" ); document.write( " The third day, he hired 5 carpenters, 3 masons, and 3 helpers.
\n" ); document.write( " If his payroll was 194 the first day, 137 the second day, and 112 the third day,
\n" ); document.write( " how much did he pay each mason a day?
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each day
\n" ); document.write( "11c + 3m + 5h =194
\n" ); document.write( "6c + 5m + 2h = 137
\n" ); document.write( "5c + 3m + 3h = 112
\n" ); document.write( ":
\n" ); document.write( "Multiply the first equation by -1, write the equations as follows
\n" ); document.write( "-11c - 3m - 5h =-194
\n" ); document.write( "6c + 5m + 2h = 137
\n" ); document.write( "5c + 3m + 3h = 112
\n" ); document.write( "--------------------Adding eliminates c and h
\n" ); document.write( "0 + 5m + 0 = 55
\n" ); document.write( "m = 55/5
\n" ); document.write( "m = $11 a day for masons \n" ); document.write( "
\n" );
