= 10
And,
10 
9
(h) We have,
b + 5 = 9
Now,
b = 9 is not a solution for the above given equation because:
When, b = 9
b + 5 = 9 + 5
= 14
And,
14 
9
(i) We have,
b + 5 = 9
Now,
b = 4 is a solution for the above given equation because:
When, b = 4
b + 5 = 5 + 4
= 9
And,
9 = 9
(j) We have,
h - 8 = 5
Now,
h = 13 is a solution for the above given equation because:
When, h = 13
h - 8 = 13 - 8
= 5
And,
5 
5
(k) We have,
h - 8 = 5
Now,
h = 8 is not a solution for the above given equation because:
When, h = 8
h - 8 = 8 - 8
= 0
And,
0 
5
(l) We have,
h - 8 = 5
Now,
h = 0 is not a solution for the above given equation because:
When, h = 0
h - 8 = 0 - 8
= -8
And,
-8 
5
(m) We have,
p + 3 = 1
Now,
p = 3 is not a solution for the above given equation because:
When, p = 3
p + 3 = 3 + 3
= 6
And,
6 
1
(n) We have,
p + 3 = 1
Now,
p = 1 is not a solution for the above given equation because:
When, p = 1
p + 3 = 1 + 3
= 4
And,
4 
1
(o) We have,
p + 3 = 1
Now,
p = 0 is not a solution for the above given equation because:
When, p = 0
p + 3 = 0 + 3
= 3
And,
3 
1
(p) We have,
p + 3 = 1
Now,
p = -1 is not a solution for the above given equation because:
When, p = -1
p + 3 = - 1 + 3
= 2
And,
2 
1
(q) We have,
p + 3 = 1
Now,
p = -2 is a solution for the above given equation because:
When, p = -2
p + 3 = - 2 + 3
= 1
