\n" ); document.write( " 8x/8=8/8
\n" ); document.write( " x=1
\n" ); document.write( "Then, I went back and input x into an original equation.
\n" ); document.write( " 2(1)+y=8
\n" ); document.write( " 2+y=8
\n" ); document.write( " y=6
\n" ); document.write( "So, this led me to the wrong answer.Thanks if you could help. \n" ); document.write( "

You can put this solution on YOUR website!
2 x + 1 y = 8 .............1
\n" ); document.write( "
\n" ); document.write( "6 x + 1 y = 3 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -1
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-2 x -1 y = -8
\n" ); document.write( "6 x + 1 y = 3
\n" ); document.write( "Add the two equations
\n" ); document.write( "4 x = -5
\n" ); document.write( "/ 4
\n" ); document.write( "x = -5/ 4
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + 1 y = 8
\n" ); document.write( "-5/2 + y = 8
\n" ); document.write( " y = 8 + 5/2
\n" ); document.write( " y = 11
\n" ); document.write( " y = 21/ 2
\n" ); document.write( " \n" ); document.write( "

\n" );
