A man wanted to get into his work building. But he had forgotten his codes. However he did remember five clues. The first digit plus the third digit equals 14. The fourth digit is one more than the second digit. The first digit is one less than twice the second digit. The second digit plus the third digit equals ten. The sum of all five digits is 30. What are the five digits and in what order?

Hey mate here's your answer
Let A = 1st number.
Let B = 2nd number.
Let C = 3rd number.
Let D = 4th number.
Let E = 5th number.
The fifth number plus the third number equals fourteen.
E + C = 14
The fourth number is one more than the second number.
D = B + 1
The first number is one less than twice the second number.
A = 2B - 1
The second number plus the third number equals ten.
B + C = 10
The sum of all five numbers is 30.
A + B + C + D + E = 30
What were the five numbers and in what order?
(1) E + C = 14
(2) D = B + 1
(3) A = 2B - 1
(4) B + C = 10
(5) A + B + C + D + E = 30
Write the equations up so that corresponding
terms line up vertically
(1) C + E = 14
(2) -B + D = 1
(3) A - 2B = -1
(4) B + C = 10
(5) A + B + C + D + E = 30
A=7, B=4, C=6, D=5, E=8
d= b+1... I m writing this as it is not seen in the picture.
I hope this helps
