Question

8,4+(-5,6-y)=-8,4+2,3

Answer 1

8,4-5,6-у=-8,4+2,3 -У=-8,4+2,3-8,4+5,6 -У=-8,9 У=8,9. Ответ: 8,9.

Answer 2

To solve this equation, we can start by simplifying both sides using the order of operations (PEMDAS).

On the left-hand side of the equation, we have:

8,4 + (-5,6 - y) =

8,4 - 5,6 + y

On the right-hand side of the equation, we have:

-8,4 + 2,3 =

-6,1

Now we can substitute these simplified expressions back into the original equation:

8,4 - 5,6 + y = -6,1

Next, we can simplify by combining like terms:

2,8 + y = -6,1

To isolate y, we can subtract 2.8 from both sides:

y = -6,1 - 2,8

y = -8,9

Therefore, the solution to the equation 8,4+(-5,6-y)=-8,4+2,3 is y = -8,9.
