Question

X-3y=-1 2x-3y=6
Método de Igualación

Answer 1

Respuesta:

X-3y=-1

2x-3y=6

-x + 3y = 1

2x - 3y = 6

x = 7

reemplazas en "x"

-x + 3y = 1

-7 + 3y = 1

3y = 1 + 7

3y = 8

y = 8/3

y = 2.67

comprobación

-x + 3y = 1

-7 + 3(8/3) = 1

-7 + 24/3 = 1

-7 + 8 = 1

1 = 1

2x - 3y = 6

2(7) - 3(8/3) = 6

14 - 24/3 = 6

14 - 8 = 6

6 = 6
