Vanpascore:let the digit be a, b, c, d, and e. (1) a = b^2 (2) b + c = 10 (3) d = b + 1 (4) c + e = 14 (5) a + b + c + d + e = 30 from 5 a+b+d+c+e = 30 subs 4 a+b+d +14 = 30 a+b+d = 16 sub 3 a+b+b+1=16 a+2b=15 sub1 b^2 + 2b - 15 = 0 (b + 5)(b - 3) = 0 b=3, since a pincode cant be negative. a = 9 b = 3 c = 7 d = 4 e = 7 |
