Chapter 3 - Equations and Problem Solving - 3.4 - Equations Involving Parentheses and Fractional Forms - Concept Quiz 3.4: 10

Answer

True

Work Step by Step

Since the person solving the problem writes the equation, simply checking the answer in the equation will not work, for the equation itself could be incorrect. It is often beneficial to ask the question: does my answer make sense? (For example, if I found that I was walking at 100 m/s, that answer would not make sense, meaning I likely made an error in my work.)
