Question

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

Answer 1

Ответ:

x = -5

Объяснение:

1.6x-(x-2.8) = (0.2x+1.5)-0.7

1.6x-x+2.8 = 0.2x+1.5-0.7

0.6x-0.2x = 0.8-2.8

0.4x = -2

x = -5

Answer 2

Let's solve the equation step by step:

1. Distribute the parentheses: 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. Simplify the equation further by subtracting 0.2x from both sides: 0.6x - 0.2x + 2.8 = 0.8

Simplifying the x-terms, we get: 0.4x + 2.8 = 0.8

4. Next, subtract 2.8 from both sides: 0.4x + 2.8 - 2.8 = 0.8 - 2.8

Simplifying the numbers, we have: 0.4x = -2.0

5. Divide both sides of the equation by 0.4 to isolate x: (0.4x) / 0.4 = -2.0 / 0.4

Simplifying further, we obtain: x = -5.0

Therefore, the solution to the equation 1.6x - (x - 2.8) = (0.2x + 1.5) - 0.7 is x = -5.0.
