Question

10x + 3y=1

8x - 4y = 20​

Answer 1

Respuesta:

______________________________________________

10x + 3y=1

Operaciones:

10 x + 3 y- 1 = 0

( 10 ) ⋅ x + ( 3 y- 1 ) = 0

x =- ( 3 y- 1 )10

x = -3/10y+1/10

Resultado final:

x = -3/10y+1/10

______________________________________________

8x - 4y = 20

Operaciones:

8 x - 4 y- 20 = 0

( 8 ) ⋅ x + ( - 4 y- 20 ) = 0

x =- ( - 4 y- 20 )8

x = -( 4 )⋅ ( - y- 5 )( 4 )⋅ ( 2 )=1/2y+5/2

Resultado final:

1/2y+5/2
