5 x/6-y/4 =-2,3r+2n=3

解答

5 \frac{x}{6} - \frac{y}{4} = - 2, 3 r + 2 n = 3

解答

r = \frac{3 - 2 n}{3}, x = \frac{- 24 + 3 y}{10}

求解步骤

[5 \cdot \frac{x}{6} - \frac{y}{4} = - 2 3 r + 2 n = 3]

对于

3 r + 2 n = 3

将

r

移到一边:

r = \frac{3 - 2 n}{3}

[5 \cdot \frac{x}{6} - \frac{y}{4} = - 2]

化简

[\frac{5 x}{6} - \frac{y}{4} = - 2]

对于

\frac{5 x}{6} - \frac{y}{4} = - 2

将

x

移到一边:

x = \frac{- 24 + 3 y}{10}

方程组的解为:

r = \frac{3 - 2 n}{3}, x = \frac{- 24 + 3 y}{10}

流行的例子

a=(81)/(3^3)-xy,b=2^3-xy

a = \frac{81}{3 ^{3}} - x y, b = 2^{3} - x y

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

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

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

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

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

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

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

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