You can put this solution on YOUR website!
2 x + 3 y = 8 .............1
\n" ); document.write( "3 x + 2 y = 7 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -2
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "-4 x -6 y = -16
\n" ); document.write( "9 x + 6 y = 21
\n" ); document.write( "Add the two equations
\n" ); document.write( "5 x = 5
\n" ); document.write( "/ 5
\n" ); document.write( "x = 1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + 3 y = 8
\n" ); document.write( "2 + 3 y = 8
\n" ); document.write( " 3 y = 8 -2
\n" ); document.write( " 3 y = 6
\n" ); document.write( " y = 2\r
\n" ); document.write( "\n" ); document.write( "x=1 ,y=2
