Question

- 3, 2 + (2, 5 - x) = - 2, 7

Answer 1

Ответ:

-3,2+(2,5-x)=-2,7

-3,2+2,5-x=-2,7

-0,7-x=-2,7

x=-2,7+0,7

x=2

Answer 2

Відповідь:

Ну тут все просто:

- 3, 2 + (2, 5 - x) = - 2, 7

(2, 5 - x) = - 2, 7 + 3, 2

2, 5 - x = 0,5

-х = 0,5 - 2,5

-х = −2

х = 2

Answer 3

To solve the equation, let's break it down step by step:

Given: 3, 2 + (2, 5 - x) = -2, 7

First, simplify the expression inside the parentheses: 2, 5 - x = (2, 5) - x = (2 - x, 5)

Now, substitute this simplified expression back into the equation: 3, 2 + (2 - x, 5) = -2, 7

Next, combine the components separately: (3 + (2 - x), 2 + 5) = (-2, 7)

Simplify further: (5 - x, 7) = (-2, 7)

Now, we can see that the y-components are already equal, so we can focus on the x-components: 5 - x = -2

To solve for x, isolate it on one side of the equation: 5 - x + x = -2 + x

Simplify: 5 = -2 + x

Subtract -2 from both sides: 5 + 2 = x

Simplify: 7 = x

Therefore, the solution to the equation is x = 7.
