You can put this solution on YOUR website!
2 x -7 y = 17 .............1
\n" ); document.write( "3 x + 4 y = 11 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 4
\n" ); document.write( "Multiply (2) by 7
\n" ); document.write( "8 x -28 y = 68
\n" ); document.write( "21 x + 28 y = 77
\n" ); document.write( "Add the two equations
\n" ); document.write( "29 x = 145.00
\n" ); document.write( "/ 29
\n" ); document.write( "x = 5
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + -7 y = 17
\n" ); document.write( "10 + -7 y = 17
\n" ); document.write( " -7 y = 17 -10
\n" ); document.write( " -7 y = 7
\n" ); document.write( " y = -1 \r
\n" ); document.write( "\n" ); document.write( "(5,-1)
\n" ); document.write( " \n" ); document.write( "
\n" );
