To solve for 'i', isolate the unknown to one side of the equation:
\n" ); document.write( "12i+18=9i
\n" ); document.write( "Subtracting 9i from both sides:
\n" ); document.write( "3i+18=0
\n" ); document.write( "Subtracting 18 from both sides:
\n" ); document.write( "3i = -18
\n" ); document.write( "Dividing both sides by 3:
\n" ); document.write( "i = -6
\n" ); document.write( "
\n" ); document.write( "
\n" );
