Question

5[x+2x| -8=4|x| -129|x|-4]x] =3-4|x| +6помогите пж​

Answer 1

Отвеt:

x =2,5

x = -5

Пошаговое объяснение:

x(2x - 5) + 5(2x - 5) = 0

(2x - 5)(x + 5) = 0

2x - 5 = 0      или         x + 5 = 0

2x = 5                           x = -5

x = 5/2                                

x = 2,5

Answer 2

It looks like you've provided an equation that needs to be solved. Let's break it down step by step.

Given Equation:

The equation you've provided is: 5(x + 2x) - 8 = 4|x| - 129|x| - 4

Step 1: Simplify the Equation

First, let's simplify the equation by combining like terms and simplifying the absolute value expressions.

5(x + 2x) - 8 = 4|x| - 129|x| - 4 5(3x) - 8 = 4|x| - 129|x| - 4 15x - 8 = 4|x| - 129|x| - 4

Step 2: Solve for x

Now, let's solve for x. We'll consider two cases: when x is positive and when x is negative.

Case 1: x is positive In this case, we can remove the absolute value symbols.

15x - 8 = 4x - 129x - 4 15x - 8 = -125x - 4 15x + 125x = 8 - 4 140x = 4 x = 4/140 x = 1/35

Case 2: x is negative When x is negative, we need to change the sign inside the absolute value expressions.

15x - 8 = -4x + 129x - 4 15x - 8 = 125x - 4 15x - 125x = 8 - 4 -110x = 4 x = 4/-110 x = -2/55

So, the solutions for x are x = 1/35 and x = -2/55.
