So, EITHER 12x − 3 = 3x + 15 OR 12x − 3 = -(3x + 15)
If 12x − 3 = 3x + 15, then we can solve the equation to get
x = 2
If 12x − 3 = -(3x + 15), then we can solve the equation to get
x = -0.8
Target question: What is the value of x?
Statement 1: x > 0
Since x equals either either
x = 2 or
x = -0.8, we can be certain that
x = 2
Since we can answer the
target question with certainty, statement 1 is SUFFICIENT
Statement 2: x is an integer
Since x equals either either
x = 2 or
x = -0.8, we can be certain that
x = 2
Since we can answer the
target question with certainty, statement 2 is SUFFICIENT
