2/3+25/6 b= 3/5+4/11 ,a=3

解答

\frac{2}{3} + \frac{25}{6} b = \frac{3}{5} + \frac{4}{11}, a = 3

解答

a = 3, b = \frac{98}{1375}

求解步骤

[\frac{2}{3} + \frac{25}{6} b = \frac{3}{5} + \frac{4}{11} a = 3]

[\frac{2}{3} + \frac{25}{6} b = \frac{3}{5} + \frac{4}{11}]

化简

[\frac{2}{3} + \frac{25}{6} b = \frac{53}{55}]

对于

\frac{2}{3} + \frac{25}{6} b = \frac{53}{55}

将

b

移到一边:

b = \frac{98}{1375}

方程组的解为:

a = 3, b = \frac{98}{1375}

x-2y=3,3x-5y=11

x - 2 y = 3, 3 x - 5 y = 11

2x+3y=13,4x+5y=23

2 x + 3 y = 13, 4 x + 5 y = 23

13x-6y=2,2x=y+6

13 x - 6 y = 2, 2 x = y + 6

x + y = 24, 2 x - y = - 6

12(x+2y)-8(2x+y)=2,(5x-6y)20(x-4y)=-10

12 (x + 2 y) - 8 (2 x + y) = 2, (5 x - 6 y) 20 (x - 4 y) = - 10
