Question

4(x-0,2)+5=2(7-x)+0,1

Answer 1

Ответ:

4(x-0,2)+5=2(7-x)+0,1

4x-0,8+5=14-2x+0,1

4x+2x=14+0,1+0,8-5

6x=9,9

x=9,9/6

x=1,65;

Answer 2

To solve the equation 4(x - 0.2) + 5 = 2(7 - x) + 0.1, you can follow these steps:

1. Distribute the constants outside the parentheses: 4x - 0.8 + 5 = 14 - 2x + 0.1

2. Combine like terms on both sides of the equation: 4x + 5 - 0.8 = 14 - 2x + 0.1

3. Simplify the constants on both sides: 4x + 4.2 = 14 - 2x + 0.1

4. Move the terms involving x to one side of the equation and the constants to the other side by adding 2x to both sides: 4x + 2x + 4.2 = 14 + 0.1

5. Combine like terms: 6x + 4.2 = 14.1

6. Subtract 4.2 from both sides to isolate the variable term: 6x = 14.1 - 4.2 6x = 9.9

7. Finally, divide both sides by 6 to solve for x: x = 9.9 / 6 x = 1.65

So, the solution to the equation is x = 1.65.
