Answer 2

Раскроем скобки

221/х - 4 - 221/х - 4 = 2

Знаки во 2-ой скобки меняются, так как перед скобкой стоит минус.

Тут нет решения. Так как 221/х - 221/х уйдут, останется выражение -8=2

Answer 3

To solve the equation (221÷x-4) - (221÷x+4) = 2, we'll follow these steps:

Step 1: Simplify the expressions on the left-hand side of the equation. Step 2: Combine like terms if possible. Step 3: Isolate the variable (x) on one side of the equation.

Let's proceed with the solution:

Step 1: Simplify the expressions (221÷x-4) - (221÷x+4)

To simplify each of these terms, we need to find a common denominator for both expressions. The common denominator is 'x'.

(221/x - 4x/x) - (221/x + 4x/x)

Now, we have:

(221 - 4x) - (221 + 4x)

Step 2: Combine like terms Now, simplify further by removing the parentheses and combining like terms:

221 - 4x - 221 - 4x

Step 3: Isolate the variable (x) Combine the like terms:

-4x - 4x = -8x

Now, the equation becomes:

-8x = 2

To isolate x, divide both sides of the equation by -8:

x = 2 / (-8)

x = -1/4

So, the solution to the equation is x = -1/4.
