Question

1/3(6х – 3) + 4(0,2х – 1)=-3

Answer 1

1/3(6х-3)+4(0,2х-1)=-3

2х-1+0,8х-4+3=0

2,8х=2

х=5/7

Answer 2

To solve the equation 1/3(6x - 3) + 4(0.2x - 1) = -3, follow these steps:

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

1/3(6x - 3) + 0.8x - 4 = -3

2. Distribute the 1/3 to the terms inside the first parentheses:

2x - 1 + 0.8x - 4 = -3

3. Combine like terms on the left side:

(2x + 0.8x) - (1 + 4) = -3

2.8x - 5 = -3

4. Add 5 to both sides of the equation to isolate the variable:

2.8x = -3 + 5

2.8x = 2

5. Now, divide both sides by 2.8 to solve for x:

x = 2 / 2.8

x ≈ 0.7143

So, the solution to the equation is approximately x ≈ 0.7143.
