Question

Add 5 double the result subtract 6 divided by 2 subtract the original number write a conjecture

Answer 1

Start with "x"

Add 5 → x + 5

double → 2(x + 5) = 2x + 10

subtract 6 → (2x + 10) - 6 = 2x + 4

divide by 2 → (2x + 4)/2 = x + 2

subtract "x" → (x + 2) - x = 2

Conjecture: Whatever number is chosen, once the given steps are followed, the result will always be 2.
