Answer 2

Step-by-step explanation:

Given,

A number is multiplied by 3 and 7 is added to it to get the result of 25.

Let us take,

The number = x

==>> x(3)+7 = 25

==>> 3x+7 = 25

==>> 3x = 25 -7

==>> 3x = 18

==>> x = 18/3

==>> x = 6

Therefore the number is 6.

Proof:

Substitute the value of x in the equation.

3x + 7 = 25

3×6+7 = 25

18+7 = 25

25 = 25

L.H.S = R.H.S

Hence proved.
