Question -:

Twice a number added to 5 gives 45. If x is the number then -:

a) Form an equation.

b) Find the value of x.

$\blue\star$ Answer -:

a) The equation = 2x + 5 = 45.

b) The value of x is 20.

Explanation -:

Given -:

The result is 45.

x is the number.

To find -:

The value of x.

Solution -:

Let the number be x.

Twice the number = 2x.

5 added to it = 2x + 5.

The result is 45.

So,

$2x + 5 = 45$

$2x = 45 - 5$

$2x = 40$

$x = \frac{40}{2}$

$x = 20$

Thus, the value of x is 20.
