Question

1,6x - (х - 2,8) = (0,2х + 1,5) - 0,7;​

Answer 1

Ответ:

1,6х-х+2,8=0,2х+1,5-0,7

2,8-0,8=1х+0,2х-1,6х

2=-0,4х

х=-5

Объяснение:

Answer 2

To solve the equation 1.6x - (x - 2.8) = (0.2x + 1.5) - 0.7, we'll follow these steps:

1. Distribute the negative sign inside the parentheses on the left side of the equation: 1.6x - x + 2.8 = 0.2x + 1.5 - 0.7

2. Combine like terms on both sides of the equation: 0.6x + 2.8 = 0.2x + 0.8

3. Subtract 0.2x from both sides to isolate the terms with x on one side of the equation: 0.6x - 0.2x + 2.8 = 0.2x - 0.2x + 0.8

   Simplifying: 0.4x + 2.8 = 0.8

4. Subtract 2.8 from both sides: 0.4x + 2.8 - 2.8 = 0.8 - 2.8

   Simplifying: 0.4x = -2

5. Divide both sides by 0.4 to solve for x: (0.4x)/0.4 = -2/0.4

   Simplifying: x = -5

Therefore, the solution to the equation is x = -5.
