Question

2) 67 - 21y = 25 с проверкой​

Answer 1

Ответ: у=2

Пошаговое объяснение:

67-21у=25

-21у=25-67

-21у=-42

у=-42÷(-21)

у=2

67-21×2=25

Answer 2

To solve the equation 67 - 21y = 25, we'll follow these steps:

Step 1: Subtract 67 from both sides of the equation: 67 - 21y - 67 = 25 - 67 -21y = -42

Step 2: Divide both sides of the equation by -21 to isolate y: (-21y) / (-21) = (-42) / (-21) y = 2

Now, let's check the solution by substituting y = 2 back into the original equation:

67 - 21(2) = 25 67 - 42 = 25 25 = 25

Since both sides of the equation are equal when y = 2, we can conclude that y = 2 is the correct solution.
