Replace each (&) with the number that makes the inequalities equivalent.

x+(&)>=25 ; x>=-12


Ok I no the answer is 37 But I need to no how to get that please.

If you don't understand my questing in words it would mean X plus what is greater then or equal to 25 is equivalent to X is greater then or equal to -12

You take the x limit from the last equation, and feed it into the first.

to find the limit, you then make it an equivalence:

-12 + (&) = 25

solve for (&).

Simply subtract the 25 from the -12 to get the answer.
