Write a fact with the same sum as 7+5

The fact having same result as 7 + 5 is 9 + 3.

Step-by-step explanation:

We are given the expression 7 + 5.

Now, the sum of the expression is 12 i.e. 7 + 5 = 12

It is required to write a fact resulting in the same sum.

So, if we consider the situation,

'Gary wants to study Math for 9 weeks and English for 3 weeks to clear the exams. How many week he need in total to study'.

Thus, the total number of weeks = Number of weeks for Math + Number of weeks for English

i.e. Total number of weeks = 9 + 3 = 12

Hence, the fact having same result as 7 + 5 is 9 + 3.

thats not a system of equations, that is a solution
