What is the answer to 3x plus 6x-2x?
There's no question there.3x + 6x - 2x is the same thing as 7x , and that's all there is to say about it.
How can you use the addition and subtraction properties of equality to produce equivalent inequalities?
This is the kind of thing to which I think you are referring. You have an equation such as 4x + 5 = 2x + 3. You can subtract 2x from both sides to obtain, 2x + 5 = 3, then add -5 to both sides to obtain 2x = -2, then divide both sides by 2 to obtain x = -1. You can do very much the same thing with an inequality such as 4x + 5 lt 2x + 3. The same steps yield x lt -1.
What is equivalent to 2x - 10 -2?
It's the same as 2x - 12
What is the answer for adding polynomials 2z plus 3z plus 5z plus 4 plus 6x-2x?
We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z. (If we have 2 of something and add three of the same thing and then 5 of the same thing we will end up with 10 of that thing).Likewise we can combine the x's.6x - 2x = 4x. (You could think of this as 6x + - 2x if this helps with the idea of "combining".)Therefore we are able to simplify this expression as:2z + 3z + 5z + 4 + 6x - 2x = 10z + 4 + 4x.
