Which of the following values of x would render the inequality 25-x<10

Answer 1

25-x<10

-x < 10 - 25

x>25-10

x>15

Answer 2

25 - x < 10

Add x to both sides

25 < x + 10

Subtract 10 from both sides:

25 - 10 < x

15 < x

Looks like any value of x greater than 15 will satisfy the inequality. Plug x= 14 (not greater than 15) then x = 16 (greater than 15) into the inequality to verify.
