Question

The sum of twice of a number and its half is 4
​

Answer 1

Answer:

The number is 4.

Step-by-step explanation:

Let the number be x

So

$2x + \frac{x}{2} = 10 \\ \\ (2 + \frac{1}{2})x = 10 \\ \\ so \: (\frac{4}{2} + \frac{1}{2})x = 10 \\ \\ \frac{5}{2}x = 10$

$\therefore \: x = \frac{2}{ \cancel5} \times { \cancel{10}} \: \: ^{2} \\ \\ = 2 \times 2 = 4 \\ \\ so \: x = 4$

Hope it helps you from my side

Answer 2

Answer:

$\frac{8}{5}$

Step-by-step explanation:

Let the number be 'x'

$2x + \frac{x}{2} = 4\\\frac{4x}{2} + \frac{x}{2} = 4\\\frac{5x}{2} = 4\\5x = 4*2\\5x = 8\\x = \frac{8}{5}$
