# What does a duck do when it flies upside down? The answer to this riddle is hidden in the equation given below:If i + 69 = 70, then i = ? If 8u = 6u + 8, then u = ?If 4a = –5a + 45, then a = ? if 4q + 5 = 17, then q = ?If –5t – 60 = – 70, then t = ? If s + 98 = 100, then s = ?If p + 9 = 24, then p = _____?If 3c = c + 12, then c = _____?If 3 (k + 1) = 24, then k = _____?For riddle answer: substitute the number for the letter it equals

Answer :

We have, i + 69 = 70

i = 70 – 69

i = 1

and 8u = 6u + 8

8u – 6u = 8

2u = 8

[dividing both side by 2]

u = 4

We have, 4a = –5a + 45

4a + 5a = 45

9a = 45

[dividing both side by 9]

a = 5

and 4q + 5 = 17

4q = 17 – 5

4q = 12

[dividing both side by 4]

q = 3

We have, –5t – 60 = –70

–5t = –70 + 60

–5t = –10

[dividing both side by –5]

t = 2

and

5p = 15 × 3

5p = 45

[dividing both side by 5]

p = 9

We have, 3c = c + 12

3c – c = 12

2c = 12

c = 6

We have, 3(k + 1) = 24

[dividing both side by 3]

k + 1 = 8

k = 8 – 1

k = 7

By substituting the number for the letter, it equals, we get
