document.write( "Question 166459: 7x-2 divided by 10 = 9x divided by 4 + 6
\n" );
document.write( "I understand that I must get rid of the fractions first but cannot determine how to do this with the fractions on both sides. If I multipy by 10 on the right side and left side do I then multipy by 4 on both sides. \n" );
