How do you solve #2x - 1 < 9#?

1 Answer

Answer:

Solve for #x# just like we do when there is an equals sign to get #x<5#

Explanation:

First we need to solve for #x#, just like we do when there is an equals sign by adding 1 to both sides:

#2x-1<9#
#2x<10#

Let's divide by 2:

#x<5#

And that's the answer. Keep in mind that if you multiply or divide by a negative number, the "fish mouth" will change direction! We didn't in this example but in future questions I'm sure you'll face that possibility.
