How do you solve the inequality #x - 1 > 2#?

2 Answers

Answer:

#x>3#

Explanation:

Let's just pretend that the inequality symbol is an equal sign. So, we have the equation

#x-1=2#

Let's solve this. Add #1# to both sides of the equation. We get

#x=3#

Now, replace the equal sign with an inequality sign.

#x>3#

Solving for an inequality is exactly like solving a normal equation (unless diving by a negative number, then the sign flips). So, #x# is any value from #4# and above.
