C. 7**Answer the following:** - Solve

a) 2(m + 2) = 20

b) 3p – 6 = 21 - The sum of three times of a number and 7 is 37. Find the number?
- Set up equation and solve

a) Manu takes a number such that half of the number is 5 more than 21.

b) Amina thinks of a number. If she takes away 2 from three times of the number, the result is 25. - Convert the following statements into equations:

a) Three times the sum of 8 and the number y is 42.

b) 7 subtracted from twice a number y is 21. - Solve the following equations:

a) 3y + 5 = 44

b) 3(m + 3) = 18

**ANSWERS:**

- 5
- -10
- 1
- 6y + 3 = 45
- 6
- a) 2(m + 2) = 20

m + 2 = 20/2

m + 2 = 10

m = 10 – 2 =8.

b) 3p – 6 = 21

3p = 21 + 6 = 27

p = 27/3 = 9 - Let the number be x.

Given 3x + 7 = 37

3x = 37 – 7

3x = 30

x = 30/3 = 10.

8.a) Let the number be x.

Given ½ x = 5 + 21

½ x = 26

x = 26 x 2 = 52.

b) Let the number be x.

3x – 2 = 25

3x = 25 + 2 = 27

x = 27/3 = 9

9.a) 3( 8 + y) = 42

b) 2y – 7 = 21

10.a) 3y + 5 = 44

3y = 44 – 5

3y = 39

y = 39/3 = 13.

b) 3(m + 3) = 18

m + 3 = 18/3

m +3 = 6

m = 6 – 3 = 3.
