I have this question thats says The solution set is {n|n>= 15} for the inequality n - 7 >= ____.

Question

the >= is greater than or equal. I need help on how to solve for the blank part.

Answer 1

{n|n>= 15}

means the set of all n such that n >= 15.

Subtract 7 from both sides. (If you do the same thing to both sides of an equation, it almost always keeps the relationship expressed in the equation true.)

n - 7 >= 15 -7
