Four different digits 1–9 are required to open a safe. The first and third numbers total ten; the second number is no more than four; the third number is a prime number; the fourth number is three less than the first; and the second number is one less than the fourth.

Can you find the four-digit safe combination?

	From the equations you get that b+c=6 a+c=10 so c can't be 3 or 5 because then b=c or a=c c can't be 7 or greater than five because then b would be negative so c has to be 2
