Question:
Make the given changes in the indicated examples of this section and then solve the resulting problems.
In Example 4, change 2t − 7 to 7 − 2t and then solve.
Data from Example 4
Solve the equation 2t − 7 = 9.
We are to perform basic operations to both sides of the equation to finally isolate t on one side. The steps to be followed are suggested by the form of the equation.
Therefore, we conclude that t = 8. Checking in the original equation, we have
