Hiya! We are learning inequalities in math class and I really do not get it. Now, go slowly, cuz I suck at math.
First off, what is an inequality? How do you solve one? Do all inequlaties have variables like x or y? And in an inequality, what does the little less than sign with a line under it mean?
Lastly, can you help me with solving this inequality?
x - __<__ 2
FYI, this- __<__ is supposed to be the less than sign with a line under it.
Thankies!

x equals 2. cuz 2 minus any other number, including zero, would be less than or equal to 2

So first of all, I think an inequality is pretty much anything that has a variable (usually X) and one of those greater than or less than signs. This includes greater or less than signs with the line under it. This line means that the other number can not only be greater than (or less than, depending on which way it's facing) it can also be equal too that number. So your inequality is saying that X is less than or equal to 2. To solve inequalities, you just treat them just like algebra problems. Your inequality has already been solved, or it is solved as much as it can be solved. X is less than or equal to 2. Hope this helps...

an inequality is basically an equation but it uses the less then <, greater than signs >. The inequality you need to solve is x is less than or equal to 2. The line under the less than sign means it can be less than or it can be equal to two. That equation seems to be in the last step. And yes all inequalities have variables as far as i know.

An inequality is just that: two things that are not equal to one another. It can contain a variable, but does not have to. Example: 2 < 4
The line underneath the less than/greater than sign means Or Equal
so using your notation:
x _<_ 2 is: x is equal or less than two.
Solving an inequality is essentially the same as solving an equation, you can add to both sides, subtract, multiply and divide. EXCEPTION: FLIP THE INEQUALITY SIGN IF YOU MULTIPLY OR DIVIDE BY A NEGATIVE NUMBER!
Post your inequality and I can walk you through it.

Ok, an inequality is easy when you get the hang of it. With one with only one variable, simply draw a horizontal line, and put zero in the middle, then write the number that x is less than or greater. Write it down and draw a dot above it. If the problem has the little line under the not equal symbol, color the dot in, if not leave the dot with a hole in it.
then draw a line from the dot pointing to the right if it is a greater than, or to the left if it is a less than.

alright so first ALL inequalities have some sort of variable (be it x or y or b or c or d oor e... etc) second _< and _> mean less than OR equal to and greater then OR equal to which simply mean the variable could equal the number so i think that your inequality is x is less than OR equal to 2 right? all you need to do is right w/e numbers are less then 2 (so 2 1 0 -1 -2 -3 etc. all the way to infinite!!) i hope i helped e-mail me if you need any further assistance

inequality- a problem where you do not have an equal sign, the answer can be a range of #s
all inequalities have variables, at least one...
the sign you are talking about indicates that the value is greater/less than OR equal to the opposing value...ex: three is less than or equal to 4...the set of numbers that make this inequality true would be (0,1,2,3,4)
your equation is missing a term (#) so it can't be solved in the form you have it written in...recheck it to see which term you are missing...
