Question 12 • Grade 7 Mathematics

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step inequality in the given form? A x plus b is greater than c

Answer
A
when b is positive
B
when A is negative
C
when A is positive
D
when b is negative

Explanation

First subtract b from both sides; this does not change the inequality symbol. Then divide both sides by A to isolate x. Dividing by a negative number reverses the inequality, so the symbol is reversed when A is negative.
