Question

12+4 |-2x-4| = 16, what is the solution set ?
​

Answer 1

Step-by-step explanation:

12+4= 16

|-2×-4|= |8|=8

16×8=128 noo

Answer 2

To find the solution set from the replacement set, plugin each value from the replacement set and evaluate both sides of the equation. If the two sides are equal, the equation is true and thus the value is a solution.

Example 1: Find the solution set of 11 - 5w = 1 from the replacement set {0, 2, 4}.
