Remember: When moving variables to the other side, the sign would change.

Check: Let's substitute the N

1.) N+45÷2=5×5 5+45÷2=5x5

N=25x2-45 50÷2=25

N=50-45 25=25

N=5 CORRECT

2.) 7+8+9+N=6² 7+8+9+12=6²

15+9+N=36 15+9+12=36

24+N=36 24+12=36

N=36-24 36=36

N=12 CORRECT

3.) N ÷7= (4+5)-7 14÷7= (4+5)-7

N ÷7= 9-7 2=9-7

N= 2x7 2=2

N=14 CORRECT

I hope you understand and i hope it helps too.
