Instructions: solve each system by the eliminsation method.\r
\n" ); document.write( "\n" ); document.write( "What is the solution for x-y=4
\n" ); document.write( " x-y=-3
\n" ); document.write( "Don't freak out, but this one has no solution. If you try to eliminate either variable both go and you get 0=7 or 0=-7. Graphically, these lines are parallel and will never intersect.
\n" ); document.write( "Multiply the top equation by -1 and add them together.
\n" ); document.write( "-1(x-y)=-1(4)--->-x+y=-4
\n" ); document.write( ":
\n" ); document.write( "-x+y=-4
\n" ); document.write( "x-y=-3
\n" ); document.write( "_______
\n" ); document.write( "0+0=-7
\n" ); document.write( "0=-7 No solution.
