Question

0,75⋅|x|+21,25=−2 срооооооочно

Answer 1

Снимаем знак модуля со знаком плюс и со знаком минус
1) 0,75х + 21,25 = -2
0,75х = -2-21,25
0,75х = -23,25
х = -31
2) -0,75х + 21,25 = -2
-0,75х = -2-21,25
-0,75х = -23,25
х = 31
Ответ: х1 = -31; х2 = 31

Answer 2

+- 31
( Переносим все , несмотря на модуль : 0,75х=-23,25
х=-31
т.к. есть модуль, то +-)

Answer 3

To solve the equation $0.75|x| + 21.25 = -2$, you'll need to isolate the absolute value term and then solve for $x$. Here's the step-by-step solution:

Step 1: Move the constant term to the other side of the equation: $0.75 |x| = -2 - 21.25$

Step 2: Combine the constants on the right side: $0.75 |x| = -23.25$

Step 3: Divide both sides by 0.75: $|x| = \frac{-23.25}{0.75}$

Step 4: Solve for $|x|$: $|x| = -31$

Since the absolute value of any real number is non-negative, $|x|$ cannot be negative. Therefore, there is no real solution for this equation.
