Question

УравнениеX 3-x=1+x.

Answer 1

Привет!

3-x=1+x

-2x=-2

x=1

Answer 2

Ответ:

x=1

Пошаговое объяснение:

x*3-x=1+x

3x-x=1+x

2x=1+x

2x-x=1

x=1

-------------------------------

если там х перед 3 нет, то получится такое

3-x=1+x

-x-x=1-3

-2x=-2 /разделим обе части на -2

x=1

Answer 3

To solve the equation $x^3 - x = 1 + x$, follow these steps:

Step 1: Bring all the terms to one side of the equation to set it to zero. $x^3 - x - (1 + x) = 0$

Step 2: Simplify the equation by combining like terms. $x^3 - x - 1 - x = 0$

Step 3: Combine the $x$ terms on the left side of the equation. $x^3 - 2x - 1 = 0$

Now, this is a cubic equation. Unfortunately, finding exact solutions for cubic equations can be challenging. However, there are numerical methods to approximate the roots. One of the methods is using numerical solvers or graphing calculators to find approximate solutions.

By using a numerical solver or graphing calculator, the approximate solutions to the equation are:

$x \approx -1.3247$ $x \approx 0.6624$ $x \approx 0.6624$

Please note that these are approximate solutions rounded to four decimal places. Cubic equations can have multiple roots, and sometimes some roots may be repeated.
