Given the universal set of nonzero REAL NUMBERS, determine the truth value of the following statement. 

e) x 3y [(3x - y = 7) ^ (2x + 4y = 3)]
Transcribed Image Text:e) x 3y [(3x - y = 7) ^ (2x + 4y = 3)]
Expert Solution
Introduction

Real numbers that are not zero simply do not contain zero. A set may be used to illustrate this. Since the letter "R" stands for real numbers, Real numbers that are not zero can be represented by R- {0}. All natural numbers are included in the universal set U, which has the form U = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. As a result, all even and odd numbers are a component of natural numbers, as we all know. As a result, Set U contains every component of Sets A and B.
