Question

2) 0,3 - (7,2 + х) = -1,5;​

Answer 1

Ответ:

х = -5,4

Пошаговое объяснение:

0,3 - 7,2 - х + 1,5 = 0

-5,4 - х = 0  

-х = 5,4   /*(-1)

х = -5,4

Answer 2

To solve the equation 0.3 - (7.2 + x) = -1.5, we can follow these steps:

1. First, simplify the equation by performing the addition within the parentheses: 0.3 - 7.2 - x = -1.5

2. Next, simplify further by subtracting 7.2 from 0.3: -6.9 - x = -1.5

3. To isolate the variable x, we'll move -6.9 to the other side of the equation by adding it to both sides: -6.9 - x + 6.9 = -1.5 + 6.9

   This simplifies to: -x = 5.4

4. To solve for x, we need to isolate it. Multiply both sides of the equation by -1 to get rid of the negative sign in front of x: (-1)(-x) = (-1)(5.4)

   This simplifies to: x = -5.4

Therefore, the solution to the equation 0.3 - (7.2 + x) = -1.5 is x = -5.4.
