You can put this solution on YOUR website!
r - 3p = 1
\n" ); document.write( "6r - p = 6
\n" ); document.write( "-------------
\n" ); document.write( "r = 3p+1
\n" ); document.write( "Substitute to solve for \"p\":
\n" ); document.write( "6(3p+1)-p = 6
\n" ); document.write( "17p= 0
\n" ); document.write( "p = 0
\n" ); document.write( "---------------------
\n" ); document.write( "Substitute in r=3p+1 to solve for \"r\":
\n" ); document.write( "r = 3*0+1 = 1
\n" ); document.write( "=======================================\r
\n" ); document.write( "\n" ); document.write( "-2x + y = 3
\n" ); document.write( "x + 4y = 3
\n" ); document.write( "--------
\n" ); document.write( "y = 2x+3
\n" ); document.write( "Substitute to solve for \"x\":
\n" ); document.write( "x + 4(2x+3) = 3
\n" ); document.write( "x + 8x+12 = 3
\n" ); document.write( "9x = -9
\n" ); document.write( "x = -1
\n" ); document.write( "------------
