Question

Решите пожалуйста уравнение.... 21-3у=2(у+3)​

Answer 1

Ответ:

2 ( у+3) = 21 - 3у

2у + 6 = 21-3Y

2у+3y = 21 - 6

5y = 15

y = 3

Ответ : у = 3 .

Answer 2

Ответ:

$21-3y=2(y+3);\\21-3y=2y+6;\\\\21-6=2y+3y\\5y=15\\y=3$

Объяснение:

Answer 3

To solve the equation 21 - 3у = 2(у + 3), we can follow these steps:

Step 1: Distribute the 2 on the right side of the equation: 21 - 3у = 2у + 6

Step 2: Combine like terms on both sides of the equation: -3у - 2у = 6 - 21 -5у = -15

Step 3: Divide both sides of the equation by -5 to isolate у: у = -15 / -5 у = 3

Therefore, the solution to the equation 21 - 3у = 2(у + 3) is у = 3.
