Question

А)13/17+х-2/17=4\17 б)4 4/11+х2 3/11=7 9/11 Помогите пожалуйста,заранее спасибо

Answer 1

13/17+х-2/17=4\17

х=4\17-13/17+2/17
x= -11/17


4 4/11+х2 3/11=7 9/11

х2 3/11=7 9/11 -4 4/11
x 25/11 = 86/11 - 48-11

x 25/11 =38/11
x=(38/11 )/ (25/11)
x =38/25

Answer 2

Solving the equation 13/17 + x - 2/17 = 4/17:

To solve the equation 13/17 + x - 2/17 = 4/17, we need to isolate the variable x on one side of the equation. Here's how we can do it step by step:

1. Combine like terms on the left side of the equation: - 13/17 - 2/17 = (13 - 2)/17 = 11/17 - The equation becomes: 11/17 + x = 4/17

2. Subtract 11/17 from both sides of the equation to isolate x: - (11/17 + x) - 11/17 = (4/17) - 11/17 - x = (4/17) - (11/17) = -7/17

Therefore, the solution to the equation 13/17 + x - 2/17 = 4/17 is x = -7/17.

Solving the equation 4 + 4/11 + x2 + 3/11 = 7 + 9/11:

To solve the equation 4 + 4/11 + x2 + 3/11 = 7 + 9/11, we need to isolate the variable x on one side of the equation. Here's how we can do it step by step:

1. Combine like terms on both sides of the equation: - 4 + 4/11 + x2 + 3/11 = 7 + 9/11 - Combine the whole numbers: 4 + 7 = 11 - Combine the fractions: 4/11 + 3/11 = 7/11 - The equation becomes: 11 + x2 + 7/11 = 7 + 9/11

2. Subtract 7/11 from both sides of the equation to isolate x2: - (11 + x2 + 7/11) - 7/11 = (7 + 9/11) - 7/11 - x2 + 11 = 9/11

3. Subtract 11 from both sides of the equation to isolate x2: - (x2 + 11) - 11 = (9/11) - 11 - x2 = (9/11) - 11 - x2 = (9/11) - (11/1) = (9 - 121)/11 = -112/11

Therefore, the solution to the equation 4 + 4/11 + x2 + 3/11 = 7 + 9/11 is x2 = -112/11.

Please note that the equation you provided is missing some information. If you meant to write x^2 instead of x2, please let me know so I can provide the correct solution.
