Question

2(4+x) +(8x-2) 3=20x-10

Answer 1

Ответ: х=-2

Пошаговое объяснение: удачи!

2(4+x) +(8x-2)3=20x-10

8+2х+24х-6=20х-10

8-6+26х=20х-10

2+26х=20х-10

26х-20х=-2-10

6х=-12

х=-12:6

х=-2

Answer 2

To solve the equation 2(4+x) + (8x-2)3 = 20x-10, you need to simplify and isolate the variable x. Let's go step by step:

1. Start by applying the distributive property to both terms inside the parentheses:

2(4+x) + 3(8x-2) = 20x - 10

2. Now, distribute the values outside the parentheses to the terms inside the parentheses:

8 + 2x + 24x - 6 = 20x - 10

3. Combine like terms on both sides of the equation:

(8 + 24x + 2x - 6) = (20x - 10)

4. Combine like terms on each side of the equation:

(26x + 2) = (20x - 10)

5. Move all terms with x to one side of the equation and constants to the other side. You can do this by subtracting 20x from both sides:

26x - 20x + 2 = -10

6. Simplify the equation:

6x + 2 = -10

7. To isolate the variable x, subtract 2 from both sides of the equation:

6x = -10 - 2

6x = -12

8. Finally, divide both sides by 6 to solve for x:

x = (-12) / 6

x = -2

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