inside the () becomes -3+b
\n" ); document.write( "now inside [] 2a-3+b multiplied by 2
\n" ); document.write( "-2[2a-3+b]=-4a+6-2b
\n" ); document.write( "what is left
\n" ); document.write( "4a-{6b-4a+6-2b}
\n" ); document.write( "multiply through by -
\n" ); document.write( "4a-6b+4a-6+2b
\n" ); document.write( "combine like terms
\n" ); document.write( "8a-4b-6
\n" ); document.write( "
