We are trying to find what a is, and to do this, we must isolate a.
\n" ); document.write( "\"-15=2.5a-5\"
\n" ); document.write( "Add 5 to both sides.
\n" ); document.write( "\"-10=2.5a\"
\n" ); document.write( "Divide 2.5 from both sides.
\n" ); document.write( "\"a=-4\"
\n" ); document.write( "
\n" );
