Chapter 3.3, Problem 52WE

To determine

To solve: The equation $(5-y)+(6-y)-(5-y)=0$

Answer to Problem 52WE

  $y=6$

Explanation of Solution

Given information:

The equation $(5-y)+(6-y)-(5-y)=0$

Calculation:

  $\begin{array}{l}(5-y)+(6-y)-(5-y)=0\\ \Rightarrow (5-y)-(5-y)+(6-y)=0\\ \Rightarrow 0+(6-y)=0[\because a-a=0]\\ \Rightarrow 6-y=0\\ \Rightarrow -y=-6\\ \Rightarrow y=6\end{array}$

Thus, the solution is $y=6$ .
