Answer:

x = 4

Step-by-step explanation:

You have to times 13 x 4 which is 52 so we have 52 + x now you times 13 times x which would be 13x now you would have the equation which is 52 + 13x now if you wanted to solve that you would do 13 divided by x and divide 52 by 13 which is 4 so x = 4 and now for commutative I dont know

Answer:

1.

13 (4 + x)

13(4)    13(x)

52+13x

Explain:  To distribute 13 to the terms inside the parentheses, I would need to multiply 13 to each of the terms.

2.

52+13x= 13x+52

Step-by-step explanation:

1. Draw lines on top of the equation from 13 to 4 and 13 to x. Draw arrows from 13(4) to 52 and 13(x) to 13x.  This shows the distribution.

Hope the answers are good enough
