Answer 2

(i) x + 1 = 20

(ii) 2x + 5 = 45

(iii) 15 = 2x + 13

(iv) 8(x - 7) = 144

(v) 52 = 2(x + 7)

(vi) 7y/7 = 1

(vii) 2x - 1 = 11

(viii) (3x + 3)/2 = 9

TO FIND:

The se.cret c.od.e.

EXPLANATION:

(i) x + 1 = 20

x + 1 = 20

x = 19

x = S = 19

(ii) 2x + 5 = 45

2x + 5 = 45

2x = 40

x = 20

x = T = 20

(iii) 15 = 2x + 13

15 = 2x + 13

2x = 2

x = 1

x = A =

(iv) 8(x - 7) = 144

8(x - 7) = 144

4(x - 7) = 72

x - 7 = 18

x = 25

x = Y = 25

(v) 52 = 2(x + 7)

52 = 2(x + 7)

x + 7 = 26

x = 19

x = S = 19

(vi) 7y/7 = 1

7y/7 = 1

7y = 7

y = 1

y = A = 1

(vii) 2x - 1 = 11

2x - 1 = 11

2x = 12

x = 6

x = F = 6

(viii) (3x + 3)/2 = 9

(3x + 3)/2 = 9

3x + 3 = 18

3x = 15

x = 5

x = E = 5

(i) (ii) (iii) (iv) (v) (vi) (vii) (viii)

Substitute the respective numbers.

= 19 20 1 25 19 1 6 5
