Question

9(2х-1)-5(11-х)=3(х+4) решите уравнение!

Answer 1

Ответ:

3.8

Объяснение:

9(2х-1)-5(11-х)=3(х+4)

18x - 9 - 55 + 5x = 3x + 12

23x - 64 = 3x + 12

20x = 76

x = 76 / 20

x = 3.8

Answer 2

Объяснение:

$9(2x - 1) - 5(11 - x) = 3(x + 4) \\ 18x - 9 - 55 + 5х = 3x + 12 \\ 23x - 64 = 3x + 12 \\ 23x - 3x = 12 + 64 \\ 20x = 76 \\ x = \frac{76}{20} = \frac{19}{5} = 3.8$

Answer 3

To solve the equation, follow these steps:

Step 1: Distribute the terms on both sides of the equation. Step 2: Combine like terms. Step 3: Isolate the variable (x) on one side of the equation. Step 4: Solve for x.

Let's go through each step:

Step 1: Expand the terms on both sides of the equation:

9(2x - 1) - 5(11 - x) = 3(x + 4)

Expand the terms inside the parentheses:

18x - 9 - 55 + 5x = 3x + 12

Step 2: Combine like terms on each side of the equation:

(18x + 5x) - (9 + 55) = 3x + 12

Combine the constants:

23x - 64 = 3x + 12

Step 3: Isolate the variable (x) on one side of the equation. To do this, move the constants to the opposite side by adding 64 to both sides and move the 3x term to the left side by subtracting 3x from both sides:

23x - 3x = 12 + 64

Simplify:

20x = 76

Step 4: Now, solve for x by dividing both sides by 20:

x = 76 / 20

x = 3.8

So the solution to the equation is x = 3.8.
