Hello,

Suppose the numbers are positive.

Let x,y,z be the numbers with x>y>z.

Since they're positive, it is obvious that x=y+z.

x-2=3z ====> x=3z+2The largest number diminished by 2 equals three times the smallest.

x+2=2(y-2) ====> x=2y-6The largest increased by 2 equals twice the result of diminishing the middle number by 2.

Solve the system :
