Question

567-(345-?)=187 как решить уровнение​

Answer 1

Ответ:

Пошаговое объяснение: ну писать зак "?" как то не культурно, так что поставим "х".

567-(345-х)=187

567-345+х=187

222+х=187

х=187-222

х=-35

Answer 2

567-(345-X)=187 -567

(345-X) =567-187 187

345-X=380 380

X=380-345

X=35

Answer 3

Solving the Equation 567 - (345 - ?) = 187

To solve the equation 567 - (345 - ?) = 187, we can follow these steps:

1. First, simplify the expression within the parentheses. 2. Then, perform the subtraction and find the value of the variable.

Step 1: Simplify the Expression Within the Parentheses

The expression within the parentheses is (345 - ?). To simplify this, we can remove the parentheses and change the subtraction to addition by reversing the signs inside the parentheses.

So, (345 - ?) becomes 345 + (-?).

Step 2: Perform the Subtraction and Find the Value of the Variable

Now, we can substitute 345 + (-?) back into the original equation and solve for the variable.

The equation becomes: 567 - (345 + (-?)) = 187

Solving further, we get: 567 - 345 - (-?) = 187

Simplify the subtraction: 222 - (-?) = 187

Add the opposite of the negative value: 222 + ? = 187

Now, solve for ?: ? = 187 - 222

? = -35

So, the value of the variable ? that satisfies the equation 567 - (345 - ?) = 187 is -35.
