Question

|1\y|=2\7 решите пожалуйста

Answer 1

|1/y|=2/7
1/y=2/7 или   1/y=-2/7
y=7/2   или     1/y=-2/7
y1=3.5       y2=-3.5

Answer 2

Solving the Equation |1\y|=2\7

To solve the equation |1\y|=2\7, we can follow these steps:

1. Isolate the Absolute Value Expression: - The absolute value expression |1\y| can be isolated by setting it equal to 2\7 and its negative counterpart, -2\7.

2. Solve for y: - After isolating the absolute value expression, we can solve for y by considering both the positive and negative cases.

Let's proceed with the solution:

Step 1: Isolate the Absolute Value Expression

The equation |1\y| = 2\7 can be rewritten as two separate equations: 1. 1\y = 2\7 2. -1\y = 2\7

Step 2: Solve for y

1. For 1\y = 2\7: - Multiplying both sides by y gives us: 1 = 2\7y - Solving for y: y = 1 / (2\7) = 7 / 2

2. For -1\y = 2\7: - Multiplying both sides by y gives us: -1 = 2\7y - Solving for y: y = -1 / (2\7) = -7 / 2

Therefore, the solutions for the equation |1\y| = 2\7 are: - y = 7 / 2 - y = -7 / 2

This completes the solution for the given equation.

Answer 3

Solving the Equation |1\y|=2\7

To solve the equation |1\y|=2\7, we can follow these steps:

1. Isolate the Absolute Value Expression: - The absolute value expression |1\y| can be isolated by setting it equal to the given value 2\7.

2. Solve for y: - Once the absolute value expression is isolated, we can solve for y.

Let's proceed with solving the equation step by step.

Step 1: Isolate the Absolute Value Expression

We start by isolating the absolute value expression |1\y| and setting it equal to 2\7.

Step 2: Solve for y

After isolating the absolute value expression, we can solve for y.

Solution

The solution to the equation |1\y|=2\7 is y = 7\2.

This solution is obtained by isolating the absolute value expression and solving for y.
