✔ 最佳答案
(44-p)/17=0
44-p=0 <= Since every number times "0" equal to 0
44=p
p=44//

check:
LHS
=(44-44)/17
=0/17
=0 <=Since "0" divide into any part , also is "0"
=RHS//
So the solution is ture!

(4-3p)/5=2
4-3p=10
3p=-6
p=-2//

Check:
LHS
=(4-3(-2))/5
=(4+6)/5
=10/5
=2
=RHS//

1. (44-p)/17=0
44-p=0
p=44

2. (4-3p)/5=-2 or (4-3p)/5=2 ???

(4-3p)/5=-2
4-3p=-10
3p=14
p=14/3

(4-3p)/5=2
4-3p=10
3p=-6
p=-2

1) 44-p=0
-p=0-44
-p=-44
p=44

2) 4-3p=-2-5
p=-7
