Answer:  The required number is 2.

Step-by-step explanation:  Given that the product of 7 and a number increased by 3 is equal to twice the number subtracted from 39.

We are to find the number.

Let x represents the given number.

Then, according to the given information, we have

[tex]7(x+3)=39-2x\\\\\Rightarrow 7x+21=39-2x\\\\\Rightarrow 7x+2x=39-21\\\\\Rightarrow 9x=18\\\\\Rightarrow x=\dfrac{18}{9}\\\\\Rightarrow x=2.[/tex]

Thus, the required number is 2.

The number is 4.

Let us assume the number be x.

As per the question

The product of 7 and a number should be increased by 3 i.e. 7x + 3.

And, the same should be equivalent to twice of the numbers that subtracted from 39 i.e. 39-2x.

So, the following equation should be

7x + 3 = 39 - 2x

7x + 2x = 39 - 3

9x = 36

x = 4

Therefore we can conclude that the number is 4.
