Questionion 3.3 Question 8, 3.3.B-6 Part 3 of 8
Find the solution(s) in the set $W$ for each of the following parts a) th A. 7 B. 5 C. 6 D. 8 b) $(11-x)-5=1$ A. 6 - 8 C. 5
0. 7 c) $7+x=x+7$ A. 7

Studdy Solution
For part c), start with the equation:
$$7 + x = x + 7$$
Subtract $x$ from both sides:
$$7 = 7$$
This is a true statement, indicating that the equation is an identity. Therefore, any real number $x$ is a solution.
The solutions are: - For part b), the solution is $x = 5$. - For part c), the solution is any real number.
