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.

   Hint (a):

   Subtract $300$ from both sides. Then, divide both sides by $150$.

   $150x+300=600\\150x=300$

   Subtract $2$ from both sides.

   $x+2=4$

   Answer (a):

   $x=2$

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. Use the same method to rewrite and solve $60t−120=300$.

   Hint (c):

   See part (b).
