4-32.

If *x* + 7 + *x* is the same as 13, can you think of a way to find the value of *x*?

To find the value of both *x*'s combined, we can subtract 7 from 13.

13 − 7 = 6

Now you know that two *x*'s are equal to 6. Can you find the value of one *x*?

Do you think you can use a similar strategy as in part (a)? Remember, try to find the value of just one *j*.

27 is the same as *j* + *j* + 15 + *j*. Can you find the value of *j*?

*j* = 4. Remember to show how you know!

Remember that 6 + 6 + 6 + 6 is the same as 6(4). This simplification should make finding *n* easier.

If two *n*'s equal 20, how much is one *n*?
