Answer 2

Ответ:

х= -2,7

Пошаговое объяснение:

-2,3 - (х + 4,6) = - 4,2

- (х+4,6)= -4,2 +2,3

- х - 4,6 = -1,9

-х= -1,9 +4,6

-х= 2,7

х= 2,7 :(-1)

х= -2,7

Answer 3

To solve the equation -2,3 - (x + 4,6) = -4,2, we need to simplify the expression on the left side and isolate the variable x.

First, let's distribute the negative sign to the terms inside the parentheses:

-2,3 - (x + 4,6) = -4,2 -2,3 - x - 4,6 = -4,2

Next, let's combine like terms:

(-2,3 - 4,6) - x = -4,2 -6,9 - x = -4,2

To isolate the variable x, we need to get rid of the -6,9 on the left side of the equation. We can do this by adding 6,9 to both sides:

-6,9 - x + 6,9 = -4,2 + 6,9

• x = 2,7

Finally, to solve for x, we can multiply both sides by -1 to change the sign:

x = -2,7

Therefore, the solution to the equation -2,3 - (x + 4,6) = -4,2 is x = -2,7.
