You can put this solution on YOUR website!
2 x + 2 y = 8 .............1
\n" ); document.write( "6 x -1 y = 10 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "2 x 2 y = 8
\n" ); document.write( "12 x -2 y = 20
\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( "2 x + 2 y = 8
\n" ); document.write( "4 + 2 y = 8
\n" ); document.write( " 2 y = 8 -4
\n" ); document.write( " 2 y = 4
\n" ); document.write( " y = 2
\n" ); document.write( " \n" ); document.write( "
