Answer 2

Answer:

Required number = 26

Step-by-step explanation:

Let a number be ' x '

Twice the number = 2x

According to the problem given,

Twice the number when decreased by 7 gives 45

=> 2x - 7 = 45

/* Add 7 both sides of the equation,we get

=> 2x - 7 + 7 = 45 + 7

=> 2x = 52

/* Divide both sides by 2, we get

=> x = 26

Therefore,

Required number = x = 26
