Question

a) If 1/2 is subtracted from a number and difference is multiplied by 4 the result is 5. What is
the number​

Answer 1

Answer-

7/4

Step-by-step explanation:

Let the number be 'x'.

Now:

[x - 1/2] * 4 = 5

⟹ 4x - 1/2 * 4 = 5

⟹ 4x - 2 = 5

⟹ 4x = 5 + 2

⟹ 4x = 7

⟹ x = 7/4

Therefore:

When 1/2 is subtracted from 7/4 and the difference is multiplied by 4, the result is 5.
