18x-24y=6,18x-24y=-45

解答

18 x - 24 y = 6, 18 x - 24 y = - 45

无解

求解步骤

[18 x - 24 y = 6 18 x - 24 y = - 45]

对于

18 x - 24 y = 6

将

x

移到一边:

x = \frac{1 + 4 y}{3}

替代

x = \frac{1 + 4 y}{3}

[18 \cdot \frac{1 + 4 y}{3} - 24 y = - 45]

化简

[6 = - 45]

6 = - 45

为假，因此方程组没有解

无解

3 x + y = 4, 2 y^{5} x + 3 y = 78

x^{2} - 31 x + 184 = 0, y^{2} - 49 y + 600 = 0

x^{2} + y^{2} = 2, 5 y - x + 7 = 0

x + y = 3, \neg 65 x + 119 y = 249

5 x - 6 y = 20, 4 x - 3 \frac{y}{4} x - 3 y = 23
