You can put this solution on YOUR website!
so you have y=-x+5
\n" ); document.write( " y=x/2-2\r
\n" ); document.write( "\n" ); document.write( "so just graph the lines...and where they intersect is your solution
\n" ); document.write( "so since both of these equations =y you can set them equal to eachother like so...\r
\n" ); document.write( "\n" ); document.write( "-x+5=x/2-2
\n" ); document.write( "so now i would clear the fraction
\n" ); document.write( "-2x+10=x-4
\n" ); document.write( "add 2x and 4 to both sides
\n" ); document.write( "14=3x
\n" ); document.write( "divide both sides by 3 and get x=14/3
\n" ); document.write( "and now, you need to solve for y lets take the first equation since there's no fractions
\n" ); document.write( "y=14/3+15/3
\n" ); document.write( "so y = 29/3\r
\n" ); document.write( "\n" ); document.write( "so your solution is (14/3,29/3) \n" ); document.write( "

\n" );
