Exercise 74 Page 109

Every equation has an $\text{equals}$ $\text{sign}$ and then values or expressions on either side of it. Key phrases, such as $\text{is},$ $\text{is equal to},$ and $\text{equals}$ tell us about the placement of the equal sign. On the left-hand side, we only have the number $\text{-}117.$ We will put that before the equals sign. On the right-hand side, we have a key word: times. This word tells us the operation that will be used in our equation. Times indicates multiplication. Putting these sides together, we have a complete equation. Finally, we can solve the equation we have written. We will do this using inverse operations and following the Properties of Equality.
