Answer 2

Х = 1

7х+4.8-10х=1.8

-3х=-3

х=1

Answer 3

To solve the equation 7x + 2(2,4 - 5x) = 1.8, we can follow these steps:

1. Distribute the 2 to the terms inside the parentheses: 7x + 2 * 2 - 2 * 5x = 1.8

2. Simplify the equation: 7x + 4 - 10x = 1.8

3. Combine like terms: (7x - 10x) + 4 = 1.8 -3x + 4 = 1.8

4. Move the constant term to the right side by subtracting 4 from both sides: -3x = 1.8 - 4 -3x = -2.2

5. Divide both sides of the equation by -3 to solve for x: x = (-2.2) / (-3)

6. Perform the division: x ≈ 0.7333 (rounded to four decimal places)

Therefore, the approximate value of x that satisfies the equation is x ≈ 0.7333.
