Answer 1

Answer:

p=11

Step-by-step explanation:

20*21-p/39+P=4

420-20p/39+P=4

420-20p=156+4p

264=24p

P=11

Answer 2

Answer:

p = 16.5

Step-by-step explanation:

20 x 21 - p / 39 - p = 4

=> 5 x 21 - p / 39 - p = 1

=> 105 - 5p = 39 - p

=> 105 - 39 = 5p - p

=> 66 = 4p

=> p = 66/4

=> p = 16.5
