Question

Let c and d be real numbers.

a. If c = 42 + d is true, then which is greater: c or d, or are you not able to tell? Explain how you
know your choice is correct.
b. If c = 42 - d is true, then which is greater: c or d, or are you not able to tell? Explain how you
know your choice is correct.

Answer 1

Explanation:

Given

c & d are real number

(a) c=42+d

c-d=42

Difference of two no is positive i.e. first no is greater than second

c>d

(b)c=42-d

c+d=42

sum of two number is 42 so we cannot tell which one is bigger
