You can put this solution on YOUR website!
b - c = 114 / 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "b + c = 170 / 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "adding the equations will eliminate c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for b, then substitute back to find c
