Срочно помогите!!! а)4/15+у/15=1 б) 8/15-у/15=0 в)19/15-у/15=1 г)1-у/15=11/15

Answer 1

А) 4/15 + у/15 = 1    б) 8/15 - у/15 = 0      в) 19/15-у/15 = 1      г) 1-у/15 = 11/15
  (4+у)/15 = 1             (8-у)/15 = 0              (19-у)/15 = 1             15-у = 11
  4+у = 15                  8-у = 0                    19-у = 15                   -у = 11-15
  у = 15-4                   -у = -8                    -у = 15-19                    у = 4
  у = 11                      у = 8                       у = 4                       1-4/15 = 11/15
4/15+11/15=1        8/15-8/15 = 0            19/15-4/15 = 1      15/15 - 4/15 = 11/15
15/15 = 1                   0 = 0                      15/15 = 1               11/15 = 11/15

Task Analysis

The given problem consists of four equations involving the variable "у". We need to solve for the value of "у" in each equation. Let's solve each equation step by step.

Equation (а): 4/15 + у/15 = 1

To solve this equation, we can start by isolating the variable "у" on one side of the equation.

1. Subtract 4/15 from both sides: 4/15 + у/15 - 4/15 = 1 - 4/15 у/15 = 1 - 4/15

2. Simplify the right side of the equation: у/15 = 15/15 - 4/15 у/15 = 11/15

3. Multiply both sides of the equation by 15 to isolate "у": (15/15) * (у/15) = (11/15) * 15 у = 11

Therefore, the solution to equation (а) is у = 11.

Equation (б): 8/15 - у/15 = 0

To solve this equation, we can follow a similar process as in equation (а).

1. Add у/15 to both sides: 8/15 - у/15 + у/15 = 0 + у/15 8/15 = у/15

2. Multiply both sides of the equation by 15 to isolate "у": (15/15) * (8/15) = (15/15) * (у/15) 8 = у

Therefore, the solution to equation (б) is у = 8.

Equation (в): 19/15 - у/15 = 1

To solve this equation, we can follow a similar process as in equation (а).

1. Subtract 19/15 from both sides: 19/15 - у/15 - 19/15 = 1 - 19/15 -у/15 = 1 - 19/15

2. Simplify the right side of the equation: -у/15 = 15/15 - 19/15 -у/15 = -4/15

3. Multiply both sides of the equation by 15 to isolate "у": (15/15) * (-у/15) = (-4/15) * 15 -у = -4

4. Multiply both sides of the equation by -1 to solve for "у": (-1) * (-у) = (-1) * (-4) у = 4

Therefore, the solution to equation (в) is у = 4.

Equation (г): 1 - у/15 = 11/15

To solve this equation, we can follow a similar process as in equation (а).

1. Subtract 1 from both sides: 1 - у/15 - 1 = 11/15 - 1 -у/15 = 11/15 - 1

2. Simplify the right side of the equation: -у/15 = 11/15 - 15/15 -у/15 = -4/15

3. Multiply both sides of the equation by 15 to isolate "у": (15/15) * (-у/15) = (-4/15) * 15 -у = -4

4. Multiply both sides of the equation by -1 to solve for "у": (-1) * (-у) = (-1) * (-4) у = 4

Therefore, the solution to equation (г) is у = 4.

Summary of Solutions:

The solutions to the given equations are: а) у = 11 б) у = 8 в) у = 4 г) у = 4
