Question

Lo necesito por método de igualacion con procedimiento por favor
A/5-b/6= -1/30
A/3-b/20=13/12

Answer 1

Respuesta:

A = 4

B = 5

Explicación:

[ Método Igualación ]

A/5-b/6= -1/30

A/5 = -1/30 + b/6

A = ( -1/30 + b/6 ) • 5

A = -5/30 + 5b/6

A = -1/6 + 5b/6

A/3-b/20=13/12

A/3 = 13/12 + b/20.

A = ( 13/12 + b/20 ) • 3

A = 39/12 + 3b/20

A = 13/4 + 3b/20

A = A

-1/6 + 5b/6 = 13/4 + 3b/20

5b/6 = 13/4 + 3b/20 + 1/6

5b/6 = 82/24 + 3b/20

5b/6 - 3b/20 = 41/12

(100b - 18b) / 120 = 41/12

82b / 120 = 41/12

82b = 41/12 • 120

82b = 410

b = 410 / 82

B = 5

A/5-b/6= -1/30

A/5-5/6= -1/30

A/5 = -1/30 + 5/6

A/5 = -1/30 + 25/30

A/5 = -1/30 + 25/30

A/5 = 24/30

A/5 = 4/5

A = 4/5 • 5

A = 4

Espero haber ayudado y agradeceria mucho ser la mejor respuesta :)
