you can just use multilecation to do division The division POE (property of equality) Allows you to divide each side of an equation by the same number. If I were solving for x in this equation, I would use the division POE -2x = 4 /-2 /-2 x = -2
It is simply 2x+20 which is an algebraic expression that has no equality sign.
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.
That all depends.Is it:ln (2x+9) = ln (5x)If it is, the solution can be found by solving 2x+9 = 5x, in which case the answer is x = 3.
2x+x-5 = 10 2x+x = 10+5 3x = 15 x = 5 and y = 0

If 4*2+2x-6=0 is what you meant, then I am going to say 2(2*1+1x-3) is your answer Edit: if solving for x then -1 is your answer, sorry I'm used to solving for multiple possibilities for x so "factor" threw me off.

It is 3 terms of an algebraic expression and it is not an equation because it has no equality sign.
You cannot because the function is not well-defined. There is no equality symbol, the function In(2x) is not defined.
6x - 2x - 3 = 31 grouping the expressions with x: 6x - 2x = 31 + 3 simplifying: 4x = 34 solving for x x = 34/4 = 8.5

Without an equality sign it can't be considered to be an equation.
In the absence of equality signs it is not possible
Without an equality sign it cannot be classed as an equation
