Question

(3891-Х) +25419=27090

Answer 1

3891-x+25419=27090
29310-x=27090
-x=27090-39310
x=2220

Answer 2

$3891 - x = 27090 - 25419 \\ 3891 - x = 1671 \\ x = 3891 - 1671$
$x = 2220$
Проверка:
(3891-2220)+25419=27090
27090=27090

Answer 3

To solve the equation (3891-Х) + 25419 = 27090, we need to isolate the variable Х on one side of the equation. Let's do that step by step:

Step 1: Combine the numbers on the left-hand side of the equation: (3891 - Х) + 25419 = 29310

Step 2: Now, to isolate Х, we need to move the constant term (25419) to the other side of the equation. We can achieve this by subtracting 25419 from both sides of the equation:

(3891 - Х) = 29310 - 25419 (3891 - Х) = 3891

Step 3: Next, isolate Х by moving the constant term (3891) to the other side. We can do this by subtracting 3891 from both sides:

-Х = 0

Step 4: Finally, to find the value of Х, we can multiply both sides by -1 to solve for Х:

Х = 0

So, the value of Х is 0.
