Notam numerele cu a, b, c, d.
a+b+c+d=33243
a-2495=b
c=2×(a+b) <=> c=2×(a+a-2495)=2×(2a-2495) => c=4a-4990
c+768=d => d=4a-4990+768 => d=4a-4222
a+b+c+d=a+a-2495+4a-4990+4a-4222= 33243 =>
=> 10a-11707=33243 => 10a=33243+11707=44950 => a=44950:10=4495
=> b=4495-2495=2000
=> c=4×4495-4990=12990
=> d=4×4495-4222=13758
Deci numerele sunt 4495, 2000, 12990, 13758.
