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.
