The two values are 47 and 29
Here, we are trying to find two values that sum up to 76, but we already have one of the values.
Let us say the values are a and b
Since they sum uo to be 76, then we have an equation describing the sum as;
a + b = 76
But since we have one of the values already, say a= 47
Then 47 + b = 76
To get b, we simply bring the other value to the right hand side of the equation and this makes it negative;
Thus;
b = 76 - 47
We proceed to subtract;
b = 29
