a=-12,b=-8/11 ,c=-7/12

解答

a = - 12, b = - \frac{8}{11}, c = - \frac{7}{12}

a = - 12, b = - \frac{8}{11}, c = - \frac{7}{12}

求解步骤

a = - 12 b = - \frac{8}{11} c = - \frac{7}{12}

[b = - \frac{8}{11} c = - \frac{7}{12}]

[c = - \frac{7}{12}]

方程组的解为:

a = - 12, b = - \frac{8}{11}, c = - \frac{7}{12}

2 \frac{x}{x} - 3 + \frac{1}{2} x = 3, x + \frac{9}{( x - 3 )} (2 x + 3) = 0

2 x - 5 y = 1, 6 - 3 x + 6 y = 21

3 x - y = 35, 2 x - 3 y = 70

3 x + 2 y = 4, - 9 x - 6 y = 12

r (x) = 100 x - 0.01 x^{2}, f (x) = 5 + 10 x + 0.02
