Hi there,
\n" ); document.write( "2x+y=8
\n" ); document.write( "y=1/2x+1/2
\n" ); document.write( "Rearrange:
\n" ); document.write( "2x + y = 8...........Eq(1)
\n" ); document.write( "-1/2x + y = 1/2......Eq(2)
\n" ); document.write( "Multiply Eq(2) by 4
\n" ); document.write( "2x + y = 8...........Eq(1)
\n" ); document.write( "-2x + 4y = = 2.......Eq(2)
\n" ); document.write( "Add Eq(1) + Eq(2)
\n" ); document.write( ".....5y = 10
\n" ); document.write( "......y = 2.
\n" ); document.write( "Substitute y = 2 into Eq(1)
\n" ); document.write( "2x + y = 8
\n" ); document.write( "2x + 2 = 8
\n" ); document.write( "2x = 8 - 2
\n" ); document.write( "2x = 6
\n" ); document.write( "x = 3
\n" ); document.write( "{2, 3}
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
