You can put this solution on YOUR website!
I am going to do this two ways, one assuming it is y=x^2 +5, the other assuming it is y=2x+5. Both of these actually can be solved. The second is first.\r
\n" ); document.write( "\n" ); document.write( "Substitute
\n" ); document.write( "6x-(2x+5)=3
\n" ); document.write( "6x-2x-5=3
\n" ); document.write( "4x-5=3
\n" ); document.write( "4x=8
\n" ); document.write( "x=2\r
\n" ); document.write( "\n" ); document.write( "y=9
\n" ); document.write( "Other equation
\n" ); document.write( "6(2)-9=12-9=3\r
\n" ); document.write( "\n" ); document.write( "If it really were y=x^2 +5\r
\n" ); document.write( "\n" ); document.write( "6x-(x^2+5)=3
\n" ); document.write( "6x-x^2-5=3
\n" ); document.write( "-x^2+6x-8=0
\n" ); document.write( "x^2-6x+8=0
\n" ); document.write( "(x-4)(x-2)=0\
\n" ); document.write( "x=4, 2 y=21 ,9
\n" ); document.write( "Second equation is 24-21=3
\n" ); document.write( "12-9=3\r
\n" ); document.write( "\n" ); document.write( "Solution set for that is (4,21) and (2,9)\r
