Question

ayuden a resolver estos problemas con el metodo de reducción xfa​ ayuden

Answer 1

Respuesta:

1. x = -1/3 y = 4/3

2. x = -4 y = 2

3. x = 2/3 y = 2/3

4. x = -3 y = 1

5. x = 0 y = -3

6. x = 3 y = -2

Explicación paso a paso:

MÉTODO DE REDUCCIÓN:

1. 5x + 2y = 1(x3) 15x + 6y = 3 21y = 28

-3x + 3y = 5(x5) -15x +15y = 25

y = 4/3 x = -1/3

2. 3x - y = -14(x2) 6x - 2y = -28 7y = 14

-2x + 3y = 14(x3) -6x +9y = 42

y = 2 x = -4

3. 5x - 2y = 2(x-1) -5x + 2y = -2 12y = 8

x + 2y = 2(x5) 5x + 10y = 10

y = 2/3 x = 2/3

4. x + 4y = 1(x2) 2x + 8y = 2 7y = 7

2x + y = -5(x-1) -2x - y = 5

y = 1 x = -3

5. 5x - y = 3(x2) 10x - 2y = 6 18y = -54

-2x + 4y = -12(x5) -10x + 20y = -60

y = -3 x = 0

6. 5x + 2y = 11(x2) 10x + 4y = 22 19y = -38

2x - 3y = 12(x-5) -10x + 15y = -60

y = -2 x = 3
