1
(i) Twice a number subtracted from 10 gives 2.
(iii) One-eighth of a number added to 6 gives 8.
(iv) Twice a number when divided by 5 gives 6.​

Answer 1

Answer:

1 . Equation is x + (x +1) = 21

2. Equation is 10 - 2x = 2

3. Equation is 1/8 + 6 = 8

4. Equation is 3x/5 = 6

Answer 2

Step-by-step explanation:

i -->

Two numbers are x and x + 1

x + x + 1 = 21

2x + 1 = 21

ii -->

Let that number be x

10 - 2x = 2

iii -->

1 / 8 * x + 6 = 8

iv -->

2x / 5 = 6
