y13=1,z13=10,0.03+j0.09=3.33-j10

解答

y 13 = 1, z 13 = 10, 0.03 + j 0.09 = 3.33 - j 10

解答

y = \frac{1}{13}, j = \frac{330}{1009}, z = \frac{10}{13}

求解步骤

y \cdot 13 = 1 z \cdot 13 = 10 0.03 + j \cdot 0.09 = 3.33 - j \cdot 10

对于

y 13 = 1

将

y

移到一边:

y = \frac{1}{13}

[z \cdot 13 = 10 0.03 + j \cdot 0.09 = 3.33 - j \cdot 10]

对于

z 13 = 10

将

z

移到一边:

z = \frac{10}{13}

[0.03 + j \cdot 0.09 = 3.33 - j \cdot 10]

对于

0.03 + j 0.09 = 3.33 - j 10

将

j

移到一边:

j = \frac{330}{1009}

方程组的解为:

y = \frac{1}{13}, j = \frac{330}{1009}, z = \frac{10}{13}

-2x+3y=7,x+7y=5

- 2 x + 3 y = 7, x + 7 y = 5

3 x + y = 2, 7 x - 2 y = 2

a=-18,a^5=9,a^9=0

a = - 18, a^{5} = 9, a^{9} = 0

3x+5y=8,7x-9y=7

3 x + 5 y = 8, 7 x - 9 y = 7

x+2y=-4,3x-2y=20

x + 2 y = - 4, 3 x - 2 y = 20
