100
Is x=10 a solution to the inequality? Explain your answer.
x>10
No, because x has to be greater than 10, but cannot equal 10.

200
Solve the inequality
6-4(6n+7)> 122
n < -6
200
Is x=-9 a solution to the inequality? Explain your answer.
x>-8
No, because x must be GREATER than -8 and -9 is less than -8.
