3a-10=4+a
\n" ); document.write( "Subtract a from both sides
\n" ); document.write( "2a-10=4
\n" ); document.write( "add 10 to both sides

\n" ); document.write( "divide each side by 2
\n" ); document.write( "a=7\r
\n" ); document.write( "\n" ); document.write( "b+3=2b-7
\n" ); document.write( "subtract b from both sides
\n" ); document.write( "3=b-7
\n" ); document.write( "add 7 to both sides
\n" ); document.write( "10=b
