While Jenna was solving the equation $150x + 300 = 600$, she wondered if she could first change the equation to $x + 2 = 4$. What do you think?

1. Solve both equations and verify that they have the same solution.

2. What did Jenna do to the equation $150x + 300 = 600$ to change it to $x + 2 = 4$?

   Hint (b):

   Are the expressions on both sides of the equation divisible by 150?

3. In the same way, rewrite $60t − 120 = 300$.

   Hint (c):

   See part (b).
