-4 x + 3 y = 25 .............1
\n" ); document.write( "Total value
\n" ); document.write( "6 x -5 y = -39 .............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 = 125
\n" ); document.write( "18 x -15 y = -117
\n" ); document.write( "Add the two equations
\n" ); document.write( "-2 x = 8
\n" ); document.write( "/ -2
\n" ); document.write( "x = -4
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-4 x + 3 y = 25
\n" ); document.write( "16 + 3 y = 25
\n" ); document.write( " 3 y = 25 -16
\n" ); document.write( " 3 y = 9
\n" ); document.write( " y = 3
\n" ); document.write( "x= -4
\n" ); document.write( "y= 3
