Question

-21-1,6x=32,9+3,3x X=?

Answer 1

так.

-21-1,6x=32,9+3,3x

-21-1,6x-3,3x=32,9

1,6x-3,3x=32,9+21

-4,9=32,9+21

-4,9=53,9

x= -11

ответ : x= -11

Answer 2

To solve for x in the equation -21 - 1,6x = 32,9 + 3,3x, follow these steps:

1. Move all the terms containing x to one side of the equation and the constant terms to the other side. To do this, add 1,6x to both sides and subtract 32,9 from both sides: -21 - 1,6x + 1,6x = 32,9 + 3,3x + 1,6x

Simplifying the equation: -21 = 32,9 + 4,9x

2. Now, isolate the term with x by subtracting 32,9 from both sides: -21 - 32,9 = 32,9 + 4,9x - 32,9

Simplifying further: -53,9 = 4,9x

3. Finally, solve for x by dividing both sides by 4,9: x = -53,9 / 4,9

Calculating the result: x ≈ -10.98

So, x is approximately -10.98.
