Question

4y - (2y : a ● c) = b y = ?

Answer 1

Объяснение:

2y:a•c = b - 4y;

2y = (b -4y):a•c

y = (b - 4y):2a • c

Answer 2

Ответ:

Объяснение:

х² -4y²)/(x+2y)=((x+2y)(x-2y)) /(x+2y)=x-2y

Answer 3

To solve for y in the equation 4y - (2y / (a ● c)) = b, you can follow these steps:

1. First, simplify the expression inside the parentheses: 2y / (a ● c)

2. Next, subtract this simplified expression from 4y on the left side of the equation: 4y - (2y / (a ● c))

   = (4y * (a ● c)) - 2y

3. Now, we have: (4y * (a ● c)) - 2y = b

4. Factor out y from the left side of the equation: y(4 * (a ● c) - 2) = b

5. Divide both sides by (4 * (a ● c) - 2) to isolate y: y = b / (4 * (a ● c) - 2)

So, the solution for y is: y = b / (4 * (a ● c) - 2)
