how do I do 120<10(x-2)?

1 Answer

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.

120<10(x-2)

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.
