Detailed Solution

Concept- In this problem, we must find the value of a number such that it is 7 more than 25. For this, we'll assume that the number we need to determine is x. Since 25 is said to be greater than x by 7, we'll add 7 to the unknown number before multiplying it by 25 to create a linear equation.
We can determine the value of the unknown number by resolving the equation.
Let x be the unknowable number.
The answer to the question states that 25 is greater than the supplied amount by 7, so we can represent this in a mathematical equation as

We now have a linear equation in which the variable x is present. To obtain the value of the variable x from the equation, we will subtract 7 from both sides of the equation.

Therefore,

is the value of the unknown number such that 25 is 7 above the number.
Hence, the correct answer is option 1.
