Пошаговое объяснение:

12x +(8-10x)=1

12x+8-10x=1

2x=1-8

2x= -7

x= -7:2

x= -3,5

Answer 2

To solve the equation 12x(8-10x) = 1, we can follow these steps:

Step 1: Distribute the 12x to the terms inside the parentheses: 12x * 8 - 12x * 10x = 1

Step 2: Simplify the equation: 96x - 120x^2 = 1

Step 3: Rearrange the equation to bring all terms to one side: 120x^2 - 96x + 1 = 0

Now, we can solve this quadratic equation using the quadratic formula:

The quadratic formula is given by: x = (-b ± √(b^2 - 4ac)) / (2a)

In our equation, a = 120, b = -96, and c = 1.

Plugging in these values into the quadratic formula, we get: x = (-(-96) ± √((-96)^2 - 4 * 120 * 1)) / (2 * 120)

Simplifying further: x = (96 ± √(9216 - 480)) / 240 x = (96 ± √(8736)) / 240 x = (96 ± 93.47) / 240

So, the two possible solutions for the equation 12x(8-10x) = 1 are: x = (96 + 93.47) / 240 ≈ 0.395 x = (96 - 93.47) / 240 ≈ 0.011

Therefore, the solutions to the equation are approximately x = 0.395 and x = 0.011.

Please note that the solutions are approximate due to rounding.
