Solve using algebraic procedures as you normally would with equations (note: except when dividing a negative number, flip the sign of the inequality!). First, isolate the variable.


Let's get rid of the 10 so we can drop the parentheses and get to x. Divide each side by 10.

12 < x - 2

Add 2 to each side.

14 < x

So, the value of x that satisfies the inequality is any value of x that is greater than (but not equal to) 14.
