In summary,To find the meaning of x in the equation 0,3x-6-x=-4,6, we need to use the order of operations and solve it step by step. First, we combine like terms to get 0,3x-x=1,4. Then, we simplify to -0,3x=1,4. To isolate x, we divide both sides by -0,3, resulting in x=2. However, when we substitute this value into the equation, we get a wrong answer. This is because we need to follow the order of operations and do the multiplication before the subtractions. When done correctly, we get x=-7,4.

0,3x-6-x=-4,6|+6
0,3x-x=1,4
-0,3x=1,4|:0,3
x=4,(6)
And I am lost now ;/ That number isn't right

This isn't right. 0,3x - x does not equal -0,3x. It may be easier to think of it as;MathNub said:
0,3x - 1x
(a variable without a coefficient really means that the coefficient is 1)
So what does this equal to?

-0,7x=1,4|:0,7
x=2
0,3*2-6-2=0,6-8=-7,4
But then we get the wrong answer.

No...MathNub said:
the bold should be -0.7, not 0.7.No...MathNub said:
you need to follow the order of operations! Ignoring that we have the wrong answer for the moment, the multiplication comes first, then the 1st subtraction, and then the 2nd subtraction. You multiplied, and then did -6-2, which is wrong.FAQ: How do I find the meaning of x in: 0,3x-6-x=-4,6 ? ;/
What is the meaning of x in this equation?
The meaning of x in this equation refers to the value that satisfies the equation, making it true.
How do I find the value of x in this equation?
To find the value of x, you can solve the equation by using algebraic principles such as combining like terms, isolating x on one side of the equation, and performing the same operation on both sides to maintain balance.
Can I solve this equation without using algebra?
Yes, there are other methods such as substitution, elimination, and graphing that can be used to solve equations without using algebra. However, these methods may not work for every type of equation.
Why does this equation have multiple solutions for x?
This equation may have multiple solutions for x because it is possible to find more than one value that satisfies the equation and makes it true. This is known as having infinite solutions.
How can I check if my solution for x is correct?
You can check your solution by substituting it back into the original equation and seeing if it makes the equation true. If it does, then your solution is correct. If not, then you may need to recheck your steps or try a different method to solve the equation.
