You can put this solution on YOUR website!
b+2a=2
\n" ); document.write( "a=-3-b
\n" ); document.write( "--------
\n" ); document.write( "Sub for a in the 1st eqn
\n" ); document.write( "b + 2(-3-b) = 2
\n" ); document.write( "b - 6 - 2b = 2
\n" ); document.write( "-b - 6 = 2
\n" ); document.write( "- b = 8
\n" ); document.write( "b = -8
\n" ); document.write( "---------
\n" ); document.write( "a = -3-b = -3 -(-8) = -3 + 8
\n" ); document.write( "a = 5
