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