WebStep-by-step solution. 1. Group all z terms on the left side of the inequality. 2. Group all constants on the right side of the inequality. 3. Isolate the z. Find the greatest common factor of the numerator and denominator: 4. WebInequalities help us understand how systems work by setting boundaries. For example, a speed limit of 30 miles per hour does not mean we have to drive exactly 30 miles per hour and, instead, establishes a boundary for what is allowable — drive more than 30 miles per hour and risk getting a ticket. This could be modelled mathematically as .
