P=3 and p=-1
First you subtract the number without a variable to the other side, so subtract one from seven, and subtract five from eight. After that just divide to make p by its self and you get the answer!!

Answer:

p=3 and p=-1

Explanation:

1) 7=1+2p

Subtract 1 on both sides to isolate x.

7=1+2p

-1 -1

6=2p

Divide both sides by 2.

6=2p

/2 /2

3=p

2) -3p+5=8

Subtract 5 on both sides to isolate x.

-3p+5=8

-5 -5

-3p=3

Divide both sides by -3.

-3p=3

/-3 /-3

p=-1

Hope this helps...have a wonderful day C:
