To solve this problem, let's break it down step by step.
Let's assume the number of local stamps Sam had in the beginning is "L".
If Sam had 80 foreign stamps and local stamps combined, we can write the equation:
L + 80 = total number of stamps (equation 1)
After giving away 13 foreign stamps and 10 local stamps, Sam had an equal number of foreign stamps and local stamps left. We can express this as:
80 - 13 = L - 10
Simplifying this equation:
67 = L - 10
Next, let's solve equation 1 and equation 2 simultaneously to find the value of L.
L + 80 = 67 + 10
L + 80 = 77
L = 77 - 80
L = -3
Based on the result, it seems there is a mistake in the initial information or in the calculations because we cannot have a negative number of stamps. Please ensure the given information is correct.
80 - 13 - 10 = 57
Since that number is odd, how could he have an equal number?
