x=t+1,y=3t+2

解答

x = t + 1, y = 3 t + 2

x = t + 1, y = 3 t + 2

求解步骤

[x = t + 1 y = 3 t + 2]

[y = 3 t + 2]

用

t

来表示

x

x = t + 1

方程组的解为:

x = t + 1, y = 3 t + 2

3 x + 2 y = 18, 3 x + y = 12

x + 2 y = 5, 3 \frac{x}{2} + 3 y = 10

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

2 x - 3 y = 2, x + 2 y = 8

5 m - 5 n = 12, 2 m + 9 n = 20
