Mathematics
1 answer:
uysha [10]3 years ago

Answer:

(D)  (a + 4)/2

Step-by-step explanation:

To solve, you need to subtract the first equation from the second.

  9p = 3a + 1

<u>-  7p = 2a - 3</u>

  2p = 1a + 4

Now, you need to rearrange the equation so that is equal to p.

2p = a + 4

(2p)/2 = (a + 4)/2

p = (a + 4)/2

This gives you answer choice D.
