The answer to your question is:

Step-by-step explanation:

1. -  

2.-

       x = 12(4) / 3

       x = 16

3.-

     3(3x + 8) = 4(15)

     9x + 24 = 60

     9x = 60 - 24

     9x = 36

     x = 4

4.-

     x = 6(45) / 11.25

     x = 24 ft

The expression equivalent are..

3x+y+2x+2+7y

Step-by-step explanation:

here we want to add the variables of the same in this case

3x    1y    

2x     7y   2

5x      8y      2
