• B. both sides of an inequality can be multiplied (or divided) by any number without affecting the sign of inequality
• C. Both (a) and (b)
• D. None of the above

Answer 1

Answer: (D)

We state the following rules for solving an inequality.
Rule 1 Equal numbers may be added to (or subtracted from) both sides of an inequality without affecting the sign of inequality.
Rule 2 Both sides of an inequality can be multiplied (or divided) by the same positive number. But when both sides are multiplied or divided by a negative number then the sign of inequality is reversed.
