Question

0,5(2y-1)-(0,5-0,2y)+1=0 решить уравнение

Answer 1

Ответ:

Пошаговое объяснение:

0,5(2y-1)-(0,5-0,2y)+1=0

y - 0,5 - 0,5 + 0,2y + 1 = 0

1,2y = 0

y = 0

Answer 2

To solve the equation, follow these steps:

Step 1: Remove the parentheses by distributing the numbers outside them.

Step 2: Combine like terms on both sides of the equation.

Step 3: Isolate the variable (y) on one side of the equation.

Step 4: Solve for y.

Let's proceed with the steps:

Step 1: 0.5(2y - 1) - (0.5 - 0.2y) + 1 = 0

Distribute 0.5 to terms inside the first parentheses and distribute -1 to terms inside the second parentheses:

y - 0.5 - (0.5 - 0.2y) + 1 = 0

Step 2: Remove the parentheses:

y - 0.5 - 0.5 + 0.2y + 1 = 0

Combine like terms:

y + 0.2y - 1 = 0. (Note: The constants -0.5 and +1 combine to give +0.5)

Step 3: Combine the y terms:

1.2y - 1 = 0

Step 4: Isolate the variable (y) by moving the constant term to the other side of the equation:

1.2y = 1

Step 5: Solve for y by dividing both sides of the equation by 1.2:

y = 1 / 1.2

y ≈ 0.8333

So, the solution to the equation is y ≈ 0.8333.
