P-1=5p+3p-8 how do I solve this?

P-1=8p-8
Add 1 to both sides
p=8p-7
Subtract 8p from both sides
-7p=-7
Divide by -7
p=1

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.
