Discuss solving equations with linear inequalities
Answer:
Addition property for inequalities: adding (or subtracting) the same quantity to both sides of an inequality never changes the solution set
Multiplicative property for inequalities: multiplying (or dividing) both sides of an inequality by a positive quantity never changes the solution set.
You must change the direction of the inequality sign when multiplying (or dividing) both sides by a negative number or when exchanging sides.
