saws x $
\n" ); document.write( "hammers y $
\n" ); document.write( "
\n" ); document.write( "1 x + 4 y = 72 .............1
\n" ); document.write( "2 x + 6 y = 114 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -3
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "-3 x -12 y = -216
\n" ); document.write( "4 x + 12 y = 228
\n" ); document.write( "Add the two equations
\n" ); document.write( "1 x = 12.00
\n" ); document.write( "/ 1
\n" ); document.write( "x = 12
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 4 y = 72
\n" ); document.write( "12 + 4 y = 72
\n" ); document.write( " 4 y = 72 -12
\n" ); document.write( " 4 y = 60
\n" ); document.write( " y = 15
\n" ); document.write( "saws $ 12
