P minus 1 equals 5 p plus 3 p minus 8

Answer:
p + 3 = 9
p - 8 = -2
Step-by-step explanation:
We know this:
p - 1 = 5
Solve for p:
p - 1 = 5 - add 1 to both sides
p = 6
Now we solve:
p + 3 = ? - Substitute p for 6
6 + 3 = 9
p - 8 = ? - Substitute p for 6
6 - 8 = -2
Answer:
p -1 = 5p + 3p -8
p=1
Step-by-step explanation:
p -1 = 5p + 3p -8
Combine like terms
p-1 = 8p -8
Subtract p from each side
p-1-p = 8p-p -8
-1 = 7p -8
Add 8 to each side
-1 +8 =7p-8+8
7 = 7p
Divide by 7
7/7 = 7p/7
1 =p
