The given equations are,
\n" ); document.write( " y=3x-18 ...(1)
\n" ); document.write( " 4x+2y=24
\n" ); document.write( "Dividing by 2, 2x+y = 12 ...(2)
\n" ); document.write( "(1)-(2)=> -2x = 3x-18-12
\n" ); document.write( " -2x-3x = -30
\n" ); document.write( " -5x = -30
\n" ); document.write( " 5x = 30
\n" ); document.write( " x = 30/5
\n" ); document.write( " x = 6
\n" ); document.write( "Substituting in (1),
\n" ); document.write( " y = 3*6-18
\n" ); document.write( " y = 18-18
\n" ); document.write( " y = 0
\n" ); document.write( "Therefore the solution is x=6, y=0 \n" ); document.write( "

\n" );
