Question 1: Given
1/10p=p-279 find
p

Answer:


p=310

Explanation:

1. Subtract
p-279 from both sides:
279-(9p)/(10)=0

2. Subtract
279 from both sides:
(9p)/(10)=-279

3. Multiply both sides by reciprocal
(10)/(9):
p=310

Question 2: Given
1/2p=p-155 find
p

Answer:


p=310

Explanation:

1. Subtract
p-155 from both sides:
155-(p)/(2)=0

2. Subtract
155 from both sides:
-(p)/(2)=-155

3. Multiply both sides by reciprocal
(2)/(1):
-p=-310

4. Multiply both sides by
-1:
p = 310
