Problem:
Which of the following equations does not have a solution?
Answer Choices:
A. (x+7)2=0
B. ∣−3x∣+5=0
C. −x​−2=0
D. x​−8=0
E. ∣−3x∣−4=0
Solution:
Because ∣−3x∣+5 is strictly positive, the equation (B)∣−3x∣+5=0​ has no solution. The solutions of equations (A), (C), (D), and (E) are −7 , −4,64, and ±34​, respectively.
