Hey homies! I need your help in trying to write diffrent inequalities. We did this in chapter 1.4. Below this is an example of the type of problems in chapter 1.4.

6x+2 ? 4*8 x=1

My question is that what are the different ways in answering this problem. If you know a way that it doesn't work, please feel free to tell me! Thanks.

What it do CT/JJ
Okay there are many symbols to put there. There is the doesn't equal sign which is = with a slash through it. The greater than sign which is the acute angle with the mouth pointing left. There is the greater than or equal to sign which is the greater than sign above a grouping symbol or the line between two numbers in fraction. Signs that could be put in the equation that would make it an untrue statement are the equal sign, the lesser than sign, a reverse greater than sign, and a lesser than or = to sign which is a reverse greater than or equal to sign. Hope I could help

Cvdv to JB

so your question was how ti di the problem right?

3b+1=132;4
the;4 is the B right? so your problem really is:

3x4+1=132
3x4 is 12 so you update your equation to

12+1=132
12+1 equals 13 so you ypdate your equation to this

13=132 but this is not a true equation so you put a slash through the equals sign.
