Question

3,5(16,5-4х)+7,45=18,3​

Answer 1

Решение:

3,5 (16,5 - 4х) + 7,45 = 18,3​;

3,5 × 16,5 - 3,5 × 4x + 7,45 = 18,3;

57,75 - 14x + 7,45 = 18,3;

- 14x = 18,3 - 57,75 - 7,45;

- 14x = - 46,9;

x = - 46,9 ÷ (- 14);

x = 3,35.

Ответ: 3,35.

Answer 3

It looks like you've provided an equation:

3.5(16.5 - 4x) + 7.45 = 18.3

To solve for the value of "x" in this equation, we'll follow these steps:

Step 1: Distribute the 3.5 on the left side of the equation: 3.5 * 16.5 - 3.5 * 4x + 7.45 = 18.3

Step 2: Simplify the left side: 57.75 - 14x + 7.45 = 18.3

Step 3: Combine the constant terms on the left side: 65.2 - 14x = 18.3

Step 4: Move the constant term to the right side: -14x = 18.3 - 65.2 -14x = -46.9

Step 5: Divide both sides by -14: x = -46.9 / -14 x = 3.35

So, the solution to the equation is x = 3.35.
