3c+2m = 10.80 (1)
\n" ); document.write( "------------------------------
\n" ); document.write( "1c+3m = 5.35 multiply both sides times 3:
\n" ); document.write( "3c+9m =16.05 (2)
\n" ); document.write( "Now subtract (2) from (1):
\n" ); document.write( "3c+2m = 10.80
\n" ); document.write( "-
\n" ); document.write( "3c+9m =16.05
\n" ); document.write( "--------------
\n" ); document.write( "0c+(-7m) = -5.25
\n" ); document.write( "-7m = -5.25 divide both sides by 7 and remember that -/- = +
\n" ); document.write( "m = 0.75 This is the cost per pound of the mints.
