5 x -1 y = 5 .............1
\n" ); document.write( "Total value
\n" ); document.write( "3 x + 5 y = -2 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 5
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "25 x -5 y = 25
\n" ); document.write( "3 x + 5 y = -2
\n" ); document.write( "Add the two equations
\n" ); document.write( "28 x = 23
\n" ); document.write( "/ 28
\n" ); document.write( "x = 23/28
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "5 x -1 y = 5
\n" ); document.write( "4 3/28 -1 y = 5
\n" ); document.write( " -1 y = 5 -4 3/28
\n" ); document.write( " -1 y = 25/28
\n" ); document.write( " y = - 25/28
\n" ); document.write( "x= 23/28
\n" ); document.write( "y= - 25/28
\n" ); document.write( " \n" ); document.write( "
