**Exercises**

**SOLVE**

Question 1.

x + 9 = 17

Answer:

x = 8,

Explanation:

Asking to solve x + 9 = 17,

So x = 17 – 9 = 8.

Question 2.

17 = s + 8

Answer:

s = 9,

Explanation:

Asking to solve 17 = s + 8,

So s = 17 – 8 = 9.

Question 3.

14 + z = 49

Answer:

z = 35,

Explanation:

Asking to solve 14 + z = 49,

So z = 49 – 14 = 35.

Question 4.

17 – f = 14

Answer:

f = 3,

Explanation:

Asking to solve 17 – f = 14,

So f = 17 – 14 = 3.

Question 5.

m – 30 = 35

Answer:

m = 5,

Explanation:

Asking to solve m – 30 = 35,

So m = 35 – 30 = 5.

Question 6.

c – 22 = 22

Answer:

c = 44,

Explanation:

Asking to solve c – 22Â = 22,

So c = 22 + 22 = 44.

Question 7.

y + 11 = 42

Answer:

31,

Explanation:

Asking to solve y + 11 = 42,

So y = 42 – 11 = 31.

Question 8.

107 = 17 + l

Answer:

I = 90,

Explanation:

Asking to solve 107 = 17 + I,

So I = 107 – 17 = 90.

Question 9.

k + 28 = 64

Answer:

k = 36,

Explanation:

Asking to solve k + 28 = 64,

So k = 64 – 28 = 36.

Question 10.

28 + u = 43

Answer:

u = 15,

Explanation:

Asking to solve 28 + u = 43,

So u = 43 – 28 = 15.

Question 11.

59 – t = 42

Answer:

t = 17,

Explanation:

Asking to solve 59 – t = 42,

So t = 59 – 42 = 17.

Question 12.

13 – a = 4

Answer:

a = 9,

Explanation:

Asking to solve 13 – a = 4,

So a = 13 – 4 = 9.

Question 13.

24 + b = 54

Answer:

b = 30,

Explanation:

Asking to solve 24 + b = 30,

So b = 54 – 24 = 30.

Question 14.

54 – e = 22

Answer:

e = 32,

Explanation:

Asking to solve 54 – e = 22,

So e = 54 – 22 = 32.

Question 15.

15 + d = 39

Answer:

d = 24,

Explanation:

Asking to solve 15 + 9 = 39,

So d = 39 – 15 = 24.
