You can put this solution on YOUR website!
You just substitute one variable's formula for the other.\r
\n" ); document.write( "\n" ); document.write( "You already have a formula for y. Use the expression in the first equation.\r
\n" ); document.write( "\n" ); document.write( "YOU DO IT! Solve for x. Finish.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Just solve both equations for y in terms of x and use slope and y-intercepts to graph and find the intersection point.

\n" ); document.write( "\n" ); document.write( "Read it as well as you can. Try on paper if you want (graph PAPER).
