Question

5(4 – х) – 16 = 8(2х – 5).

Answer 1

Ответ:

Пошаговое объяснение:

20-5x-16=16x-40

-5x-16x=-40-20+16

-21x=-44

x=2.095

Answer 2

To solve the equation 5(4 - x) - 16 = 8(2x - 5), you'll want to simplify and isolate the variable x. Here are the steps to solve for x:

1. Distribute the numbers on the left and right sides of the equation:

5(4 - x) - 16 = 8(2x - 5)

Expand the expressions within the parentheses:

20 - 5x - 16 = 16x - 40

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

(20 - 16) - 5x = 16x - 40

4 - 5x = 16x - 40

3. Move all terms with x to one side of the equation by adding 5x to both sides:

4 - 5x + 5x = 16x - 40 + 5x

4 = 21x - 40

4 + 40 = 21x

44 = 21x

4. Finally, isolate x by dividing both sides by 21:

44/21 = (21x)/21

x = 44/21

So, the solution to the equation is:

x = 44/21

Answer 3

To solve the equation 5(4 - x) - 16 = 8(2x - 5), you'll want to simplify and isolate the variable x. Here are the steps to solve it:

1. Distribute the constants on the left side and right side of the equation:

   5 * 4 - 5x - 16 = 8 * 2x - 8 * 5

2. Simplify the equation:

   20 - 5x - 16 = 16x - 40

3. Combine like terms on each side of the equation. On the left side, combine 20 and -16, and on the right side, combine -5x and 16x:

   4 - 5x = 16x - 40

4. Move the variable terms (in this case, -5x) to the left side by adding 5x to both sides of the equation:

   4 = 16x - 40 + 5x

5. Combine the variable terms on the right side:

   4 = 21x - 40

6. Add 40 to both sides of the equation to isolate the variable term:

   4 + 40 = 21x

7. Simplify the equation further:

   44 = 21x

8. Finally, solve for x by dividing both sides by 21:

   x = 44/21

So, the solution to the equation is:

x = 44/21
