Answer 2

Based on the provided equation, it seems like you are looking for the value of the variable "X" in a series of equations. Let's break down the equation step by step and solve for "X".

Equation 1:

11 * Х + 409 = 65 * 3 + 700 * 260

To solve for "X", we need to isolate it on one side of the equation. Let's simplify the equation:

11 * Х + 409 = 195 + 182,000

Combining like terms:

11 * Х + 409 = 182,195

Subtracting 409 from both sides:

11 * Х = 182,195 - 409

11 * Х = 181,786

Dividing both sides by 11:

Х = 181,786 / 11

Х ≈ 16,526.909

Therefore, the value of "X" in Equation 1 is approximately 16,526.909.

Equation 2:

6 * Х - 612 = 420 / 6 * 9 + 2694

Let's simplify the equation:

6 * Х - 612 = 70 + 2694

Combining like terms:

6 * Х - 612 = 2,764

Adding 612 to both sides:

6 * Х = 2,764 + 612

6 * Х = 3,376

Dividing both sides by 6:

Х = 3,376 / 6

Х = 562.667

Therefore, the value of "X" in Equation 2 is approximately 562.667.

Equation 3:

2 * X * 30 = (502 + 28) * 3 + 45 * X

Let's simplify the equation:

2 * X * 30 = 530 * 3 + 45 * X

Multiplying:

60 * X = 1,590 + 45 * X

Subtracting 45 * X from both sides:

60 * X - 45 * X = 1,590

Combining like terms:

15 * X = 1,590

Dividing both sides by 15:

X = 1,590 / 15

X = 106

Therefore, the value of "X" in Equation 3 is 106.

Equation 4:

20 * 5 - 10 * X = 200

Let's simplify the equation:

100 - 10 * X = 200

Subtracting 100 from both sides:

-10 * X = 100

Dividing both sides by -10:

X = 100 / -10

X = -10

Therefore, the value of "X" in Equation 4 is -10.

Equation 5:

680 - 40 * X + 2 * 560 = (40 + 30) / 10

Let's simplify the equation:

680 - 40 * X + 1,120 = 70 / 10

Combining like terms:

680 - 40 * X + 1,120 = 7

Subtracting 1,120 from both sides:

-40 * X = 7 - 1,120

-40 * X = -1,113

Dividing both sides by -40:

X = -1,113 / -40

X ≈ 27.825

Therefore, the value of "X" in Equation 5 is approximately 27.825.

I hope this helps! Let me know if you have any further questions.
