You can put this solution on YOUR website!
y = x+ 2
\n" ); document.write( "6x – 4y = –10
\n" ); document.write( "substitute the first into the second.
\n" ); document.write( "6x-4(x+2)= -10
\n" ); document.write( "6x-4x-8=-10
\n" ); document.write( "2x=-2
\n" ); document.write( "x=-1
\n" ); document.write( "y=1 One solution, (-1,1)
\n" ); document.write( "That is none of the choices above, but it is the right answer. Perhaps the choices were not correct or the equations are different from these.
