Question

2x-3x=-6x-8 Ответ моего решения:-1,6 Но в поле правильных ответов написано:1,6. Я не понимаю, в чём ошибка. Помогите, пожалуйста.

Answer 1

2х-3х = -6х-8
-х+6х= -8
5х = -8
Х= -8:5
Х= - 1,6
-----------
2*(-1,6)-3*(-1,6) = -6*(-1,6)-8
-3,2 +4,8 = 9,6 -8
1,6 = 1,6

Answer 2

2х-3х=-6х-8
2х-3х+6х=-8
5х=-8
х=-8:5
х=-1,6

Если условие записано верно, то ответ: -1,6. Видимо опечатка в ответах

Answer 3

Understanding the Equation

The given equation is 2x - 3x = -6x - 8. You have solved it and obtained the answer -1.6, but the correct answer given is 1.6. Let's go through the steps to understand the error.

Solving the Equation

To solve the equation, let's start by simplifying both sides of the equation step by step.

Step 1: Combine like terms on the left-hand side: 2x - 3x = -x

Step 2: Combine like terms on the right-hand side: -6x - 8 = -6x - 8

Identifying the Error

It seems that the error might have occurred during the simplification of the equation. Let's verify the steps to see where the mistake might have happened.

Verifying the Solution

The mistake might have occurred during the simplification of the equation. Let's verify the steps to see where the mistake might have happened.

The correct simplification of the equation is as follows: 2x - 3x = -x -x = -6x - 8

Now, let's solve for x: -x = -6x - 8 -x + 6x = -8 5x = -8 x = -8 / 5 x = -1.6

It seems that the mistake occurred during the simplification of the equation. The correct solution to the equation 2x - 3x = -6x - 8 is x = -1.6, which matches your initial solution.

So, it appears that the correct answer is indeed -1.6. If the system is indicating 1.6 as the correct answer, there might be an error in the system. I would recommend reaching out to your instructor or the system administrator to address this discrepancy.

I hope this helps clarify the situation! If you have any further questions or need additional assistance, feel free to ask.
