You can put this solution on YOUR website!
If you solved the 1st equation for y, you would get:\r
\n" ); document.write( "\n" ); document.write( "\"4x%2B4y=4\"
\n" ); document.write( "\"4y=4-4x\" Subtract 4x from both sides
\n" ); document.write( "\"y=1-x\" Divide both sides by 4\r
\n" ); document.write( "\n" ); document.write( "Do the same for the 2nd equation
\n" ); document.write( "\"x%2By=1\"
\n" ); document.write( "\"y=1-x\" Subtract x from both sides\r
\n" ); document.write( "\n" ); document.write( "Since they are the same equation, they will have an infinite number of solutions. Here's the graph:\r
\n" ); document.write( "\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C1-x%29+\" Graphs of \"y=1-x\". There should be 2 graphs, but they overlap.
