This is a question that you only really get the wrong answer of "the case costs 10 euros" when you ask it in person (and you try to get them to answer it very quickly). The psychology behind people giving the wrong answer is very interesting though. It doesn't really show any level of intelligence if you get it right or wrong. It can show some character of someone however, like a person's tendency to act rashly or be more thoughtful.

Phone price = x. Case price = y.
Phone + case = 110. So x + y = 110. x = 110 - y.
Phone alone is 100 euro more than both. So x = 100 + x + y at the same time.
Which means 100 + x + y = 110 - y. 100 + x = 110 - 2y. x = 10 - 2y.
110 - y = 10 - 2y. 100 = -y. So y = -100.
x = 110 + 100 = 210.
Phone price = 210 euros. Case price is -100 euros (you're getting paid when "buying it").
Both are 110 euros, phone is worth 100 euro more than phone + case. Solved.

Y = 100 + X
X + Y = 110
Use substitution.
X + (100 + X) = 110
2X = 10
X = 5
Y = 105
Phone 105, Case 5.

nice trick, I thought it was 10 at first

5, these kids who wrote 10 lines of equations are cringe
x+x+100=110 /- 100
2x = 10 /2
x = 5
