Elementary Symmetric Polynomials prove to be useful substitutions for this system of equations

Given x^3 + y^3 = 1933, (x+y)(x+1)(y+1)=2022.
Evaluate x+y. This was a dare math problem presented by @learnwithchristianekpo6005 as an Olympiad problem, but I could not verify which competition. ESP were used as simplifying substitutions along with the rational zero theorem and the less than square root primality test
