Answer:
Step-by-step explanation:
Remark
The last digit is 1 3 5 7 9 because the last digit is odd.
The first digit must be a 3 because the number is between 300 and 350
Let the first digit = x
Let the second digit = y
Let the third digit = z
x + y = z
x + y + z = 14 Substitute z for x + y
z + z = 14 Combine
2z = 14 Divide by 2
2z/2 = 14/2
z = 7
The first digit is 3 and the third digit = 7
The middle digit is 3 less than the last digit.
y = 7 - 3 = 4
Answer
