Question

3)-(x+2,3)+3,7 = 4,7​

Answer 1

-(х+2,3)+3,7=4,7   | минус пока что перед скобкой оставляем и переносим просто число.

-(х+2,3)=4,7-3,7

-(х+2,3)=1             | теперь мы переводим знаки в скобке, потому что перед всей скобкой у нас был минус. Там где был плюс станет минус, а где был минус станет плюс.

-х-2,3=1

-х=1+2,3.

-х=3,3.

х =-3,3.

Ответ: х=-3,3.

Answer 2

-x-2,3+3,7=4,7
-x=4,7-3,7+2,3
-x=3,3
x=-3,3

Answer 3

To solve the equation (3 - (x + 2), 3) + (3, 7) = (4, 7), we need to perform vector addition on the left-hand side of the equation.

Let's break down the equation step by step:

(3 - (x + 2), 3) + (3, 7) = (4, 7)

First, let's simplify the expression (3 - (x + 2), 3):

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

Now, we can perform vector addition component-wise:

(3 - x - 2 + 3, 3 + 7) = (4, 7)

Simplifying further:

(4 - x, 10) = (4, 7)

Now, we can equate the corresponding components:

4 - x = 4 (from the x-component) 10 = 7 (from the y-component)

From the second equation, we can see that 10 is not equal to 7, which means there is no solution to the equation. The original equation is inconsistent, and there is no value of x that satisfies the equation (3 - (x + 2), 3) + (3, 7) = (4, 7).
