❄❄❄ EXPLANATION ❄❄❄

➡ Firstly, we have to hold the two unknown numbers as "x" and "y".

➡ Now we have to go through the rules of linear equations. Thats what we have done.

➡ We get the actual condition and we obtain the value of second number "y" here.

➡ Since the first number is 7 less than y, the value of first number is also easily obtained after getting the value of y.

➡ Thus, the above numerical is solved.

==================================

Let the two numbers be x and y.

Firstly, its stated that x+y = 45

Again, as per question, y-7+y = 45

So, y-7+y = 45
=> 2y = 45+7
=> y = 52/2 = 26.

Hence, first number = y-7 = 26-7 = 19 (Ans.)
