Answer :

Let's solve this problem step by step.

We are given that when 97,287 is added to a certain number, the sum is 1,028,390. We need to find the certain number.

1. Set up the equation based on the given information:
[tex]\[ \text{certain number} + 97,287 = 1,028,390 \][/tex]

2. To find the certain number, we need to isolate it on one side of the equation. We do this by subtracting 97,287 from both sides of the equation:
[tex]\[ \text{certain number} = 1,028,390 - 97,287 \][/tex]

3. Perform the subtraction to find the value of the certain number:
[tex]\[ 1,028,390 - 97,287 = 931,103 \][/tex]

So, the certain number is 931,103.
