5x-7y=9 .............1
\n" ); document.write( "4x-3y=33.............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by -4
\n" ); document.write( "Multiply (2) by 5
\n" ); document.write( "-20x+28y=-36
\n" ); document.write( "20x-15y=165
\n" ); document.write( "
\n" ); document.write( "Add the two equations
\n" ); document.write( "
\n" ); document.write( "13y=129
\n" ); document.write( "/13
\n" ); document.write( "
\n" ); document.write( "y=9.92
\n" ); document.write( "Plug value of y in
\n" ); document.write( "5x-7y=9
\n" ); document.write( "5x-69.46 = 9
\n" ); document.write( "5x=78.46
\n" ); document.write( "/5
\n" ); document.write( "x=15.69
\n" ); document.write( " \n" ); document.write( "
