4 x + 3 y = 1 .............1
\n" ); document.write( "2 x + 5 y = 11 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -5
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "-20 x -15 y = -5
\n" ); document.write( "6 x 15 y = 33
\n" ); document.write( "Add the two equations
\n" ); document.write( "-14 x = 28
\n" ); document.write( "/ -14
\n" ); document.write( "x = -2
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "4 x + 3 y = 1
\n" ); document.write( "-8 + 3 y = 1
\n" ); document.write( " 3 y = 1 + 8
\n" ); document.write( " 3 y = 9
\n" ); document.write( " y = 3
\n" ); document.write( " \n" ); document.write( "
