Question

2(x-0,4)= x- 5

Answer 1

2(х - 0,4) = 1/6х - 5
2х - 0,8 = 1/6х - 5
2х - 1/6х = -5 + 0,8
1 6/6х - 1/6х = -4,2
1 5/6х = -4 2/10
11/6х = -4 1/5
11/6х = -21/5
х = -21/5 : 11/6
х = -21/5 * 6/11
х = -126/55
х = -2 16/55

Answer 2

To solve the equation 2(x - 0.4) = x - 5, you can follow these steps:

1. Distribute the 2 to the terms inside the parentheses: 2x - 2(0.4) = x - 5

2. Simplify the expression: 2x - 0.8 = x - 5

3. Group the x terms on one side of the equation and the constant terms on the other side: 2x - x = -5 + 0.8

Simplifying further: x = -5 + 0.8

4. Combine the constant terms: x = -4.2

Therefore, the solution to the equation is x = -4.2.
