Question

Si se cumple: (2x + 3y ; 10) = (18 ; 2x – 3y), indique el valor de: (x ; 3y – 1).

Answer 1

Respuesta:

La respuesta es (7; 3)

Explicación paso a paso:

2x+ 3y = 18 +

2x - 3y = 10

_________

4x = 28

X = 28/4

X = 7

2x + 3y = 18

2(7) + 3y = 18

3y = 18-14

3y = 4

Y = 4/3

(x ; 3y - 1)

3(4/3)-1 = 4-1 = 3
