Answer 1

12-x:1,05=1,8

12-x=1,8•1,05

12-x=1,69

x=12-1,69

x=11,31

Answer 2

To solve the equation $12 - x \times 1.05 = 1.8$, we need to find the value of $x$.

Let's solve it step by step:

1. First, subtract 1.8 from both sides to isolate the term with $x$: $12 - x \times 1.05 - 1.8 = 0$

2. Now, let's combine the numbers on the left side of the equation: $10.2 - x \times 1.05 = 0$

3. Next, we want to get rid of the term with $x$ multiplied by 1.05. To do that, we divide both sides of the equation by 1.05: $\frac{10.2 - x \times 1.05}{1.05} = \frac{0}{1.05}$

4. Simplify the left side of the equation: $9.71428571 - x = 0$

5. Finally, isolate $x$ by subtracting 9.71428571 from both sides: $x = 9.71428571$

So, the value of $x$ is approximately 9.71 (rounded to two decimal places).

Now, you mentioned that giving this answer yields 37 points. It's not clear what context or system is being used to assign points based on the value of $x$. If there is additional information or a specific scoring system, please provide more details, and I'll do my best to address it.
