solvefor x,2^5x+2^8y=2^{13}z

解答

求解

x, 2^{5} x + 2^{8} y = 2^{13} z

x = 8 (32 z - y)

求解步骤

2^{5} x + 2^{8} y = 2^{13} z

2^{5} = 32

32 x + 2^{8} y = 2^{13} z

2^{8} = 256

32 x + 256 y = 2^{13} z

2^{13} = 8192

32 x + 256 y = 8192 z

将

256 y

到右边

32 x = 8192 z - 256 y

两边除以

32

x = 8 (32 z - y)

40 = x \cdot 1 + 0.5 \cdot 3 x

so l v e f or x, 5 x + 3 y - 30 = 3 x - 5 y + 16 - 0

so l v e f or y, x = \frac{( y + 12 )}{- 3}

2 n + 3 n = 1, 3, 5, 7

x - \frac{5}{6} = \frac{16}{42} + \frac{( - 8 )}{56}
