You can put this solution on YOUR website!
3 x -4 y = 32 .............1
\n" ); document.write( "1 x + 3 y = -11 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 3
\n" ); document.write( "Multiply (2) by 4
\n" ); document.write( "9 x -12 y = 96
\n" ); document.write( "4 x + 12 y = -44
\n" ); document.write( "Add the two equations
\n" ); document.write( "13 x = 52.00
\n" ); document.write( "/ 13
\n" ); document.write( "x = 4
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + -4 y = 32
\n" ); document.write( "12 + -4 y = 32
\n" ); document.write( " -4 y = 32 -12
\n" ); document.write( " -4 y = 20
\n" ); document.write( " y = -5
\n" ); document.write( " \n" ); document.write( "

\n" );
