3 x + 2 y = 42 .............1
\n" ); document.write( "Total value
\n" ); document.write( "3 x + 8 y = 96 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -4
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-12 x -8 y = -168
\n" ); document.write( "3 x + 8 y = 96
\n" ); document.write( "Add the two equations
\n" ); document.write( "-9 x = -72
\n" ); document.write( "/ -9
\n" ); document.write( "x = 8
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + 2 y = 42
\n" ); document.write( "24 + 2 y = 42
\n" ); document.write( " 2 y = 42 -24
\n" ); document.write( " 2 y = 18
\n" ); document.write( " y = 9
\n" ); document.write( "x= 8
\n" ); document.write( "y= 9
