Question

(3x - 2y = 1
(x + 1y = 19​

Answer 1

Respuesta:

X= 3

Y= 4

Explicación paso a paso:

(3x - 2y = 1

(x + 4y = 19

(2)3x -(2) 2y = 1(2)

X + 4y = 19

6x - 4y = 2

X +4y = 19

6x + x = 19 + 2

7x = 21

X= 21/7

X=3

Y=

3(3) - 2y = 1

9 - 2y = 1

-2y = 1-9

-2y = - 8

Y = 8/2

Y= 4

Comprobación

3(3) - 2(4) = 1

9 - 8 = 1

(3) + 4(4) = 19

3 + 16 = 19
