Question

3 + p = 8 I just don't know the steps to do this! Help me

Answer 1

Solution

1) Subtract 3 from both sides 
p=8−3

2) Simplify 8−3 to 5 
p=5

Answer 2

OK.  Watch me carefully.  I'll go slow.

You said that                               3 + p = 8

Subtract  3  from each side:      0 + p = 5

                                                           p = 5 .
