Question

x-5y=-10
2x-4y=-2
Resultado?​

Answer 1

X = 5

Y = 3

Explicación paso a paso:

Método de igualación

X = -10 + 5y

X = (-2 + 4y) / 2

-10 + 5y = (-2 + 4y) / 2

-10 + 5y = -2/2 + 4y/2

-10 + 5 y = -1 + 2y

5y - 2y = -1 + 10

3y = 9

y = 9/3

y = 3

X= -10 + 5 . 3 = -10 + 15 = 5

X= (-2 + 4 . 3) / 2 = (-2 + 12) /2 = 10 /2 = 5

x - 5y = -10

5 - 5.3 = -10

5 - 15 = -10

-10 = -10

2x - 4y= -2

2.5 - 4.3 = -2

10 - 12= -2

-2 = -2
