Question

-2(2x+4)+(6x+8)=4(5x-2)-(5x+8)-8x-2

Answer 1

-2(2x+4)+(6x+8)=4(5x-2)-(5x+8)-8x-2;
-4х-8+6х+8=20х-8-5х-8-8х-2;
2х=7х-18;
18=7х-2х;
5х=18;
х=18:5
х=3,6
Ответ:3,6

Answer 2

Let's solve the equation step by step:

-2(2x+4) + (6x+8) = 4(5x-2) - (5x+8) - 8x - 2

First, distribute the constants on both sides of the equation:

-4x - 8 + 6x + 8 = 20x - 8 - 5x - 8 - 8x - 2

Now, combine like terms on both sides:

(6x - 4x) + (-8 + 8) = (20x - 5x - 8x) - 8 - 2

Simplify further:

2x + 0 = 7x - 10

Now, move the 7x term to the left side of the equation and the 0 term to the right side by subtracting 7x from both sides:

2x - 7x = -10

Simplify:

-5x = -10

Now, divide both sides by -5 to solve for x:

x = -10 / -5 x = 2

So, the solution to the equation is x = 2.
