Question

A) -3(1-y)+3(1-2y)=9​

Answer 1

Ответ:

=-3+3у+3-6у=9

3 і 3 знищуються

Виходить =3у-6у

-3у=9

У = - 3

Answer 2

Let's solve the equation:

A) -3(1-y) + 3(1-2y) = 9

First, distribute the -3 and 3 on the left side of the equation:

-3 + 3y + 3 - 6y = 9

Now, combine like terms:

(3y - 6y) + (-3 + 3) = 9

-3y + 0 = 9

Now, add 3y to both sides of the equation to isolate the variable y:

-3y + 3y = 9 + 3y

0 = 9 + 3y

Now, subtract 9 from both sides:

0 - 9 = 9 + 3y - 9

-9 = 3y

Finally, divide both sides by 3 to solve for y:

-9 / 3 = 3y / 3

-3 = y

So, the solution to the equation A) is y = -3.
