Question

3x+3y=3
3x-3y=1
Método de reducción s

Answer 1

Respuesta:

$x = \frac{2}{3}$

$y = \frac{1}{3}$

Explicación paso a paso:

3x+3y=3

3x-3y=1

3x+3x = 3 + 1

6x = 4

X = 4/6

X= 2/3

3x+3y=3

(-1)3x-3y(-1)=1 (-1)

3x + 3y = 3

-3x + 3y = - 1

3y + 3y = 3 - 1

6y = 2

Y= 2/6

Y= 1/3

Comprobación

3x+3y=3

3(2/3) + 3(1/3) = 3

(6/3)+ (3/3) = 3

2 + 1 = 3

3x-3y=1

3(2/3) - 3(1/3) = 1

(6/3) - (3/3) = 1

2 - 1 = 1
