Question

P minus 1 equals 5 p plus 3 p minus 8

Answer 1

p + 3 = 9

p - 8 = -2

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 2

p -1 = 5p + 3p -8

p=1

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
