Respuesta:
n = 1/5; m = 9/10
Explicación paso a paso:
6m - 7n = 4
Despejamos "N":
-7n = 4 - 6m
7n = 6m - 4
n = (6m - 4)/7 ... (1)
Luego:
2m - 14n = -1
Despejamos "N":
-14n = -1 -2m
14n = 2m + 1
n = (2m + 1)/14 ... (2)
Igualamos 1 y 2:
(6m - 4)/7 = (2m + 1)/14
6m - 4 = (2m + 1)/2
12m - 8 = 2m + 1
10m = 9
m = 9/10
∴ 14n = 2m + 1
14n = 2(9/10) + 1
14n = 9/5 + 1
14n = 9/5 + 5/5
14n = 14/5
n = 1/5
Respuesta:
m = 9/10 n = 1/5
Explicación paso a paso:
6m-7n=4 => m = 4 + 7n/6
2m-14n=-1 => m = -1 + 14n/2
4+7n/6 = -1 + 14n/2
8+14n = -6 + 84n => -70n = -14 => n = 1/5
6m - 7(1/5) = 4
6m = 4 + 7/5
6m = 27/5 => m = 27/5x6 => m = 9/10
Comprobación:
6(9/10) - 7(1/5) = 4
27/5 - 7/5 = 4 => 20/5 = 4 => 4 = 4
2(9/10) - 14(1/5) = -1
9/5 - 14/5 = -1 => -5/5 = -1 => -1 = -1
RPTA: m = 9/10 n = 1/5
