a=6,b=4,c=7

解答

a = 6, b = 4, c = 7

a = 6, b = 4, c = 7

求解步骤

a = 6 b = 4 c = 7

[b = 4 c = 7]

[c = 7]

方程组的解为:

a = 6, b = 4, c = 7

(6) 2 x - 2 y = y, 4 x + 3 y = - 2

x + 2 y = 5, 2 x - 3 y = 4

(2 a - 1) x + 3 y - 5 = 3, x + (b - 1) y - 2 = 0

2 x + y + z = 4, x + y + 2 z = 4, x - y - z = - 1

\frac{4}{3} x - y = 2, 2 x - y = 3
