From the math problem, the first digit is clear: it is 1. You need to find the value of the digits 2, 3, and 4. To begin solving the problem, give a variable to each digit.
a = b+2
b = c+2
c = (a+b) – 10
Put the values of a and b into c.
c = [(b+2) + (c+2)] – 10
c = (4+b+c) – 10
c = -6 + b + c
b = 6 (digit #3)
Put the b value into a variable.
a = 8 (digit #2)
Put the values of a and b into the c variable.
c = 4 (digit #4)
Put all the digits together, and you will get the 1864code. Alternatively, you can try to solve it logically by keeping the last digit positive. The only numbers that work in this sense are 6 and 8.
