solvefor h,h(3/5)^2+k(3/5)-12=0

解答

求解

h, h (\frac{3}{5})^{2} + k (\frac{3}{5}) - 12 = 0

解答

h = \frac{5 ( - k + 20 )}{3}

求解步骤

h (\frac{3}{5})^{2} + k (\frac{3}{5}) - 12 = 0

化简

h (\frac{3}{5})^{2} + k (\frac{3}{5}) - 12 : \frac{9}{25} h + \frac{3}{5} k - 12

\frac{9}{25} h + \frac{3}{5} k - 12 = 0

将

\frac{3}{5} k

到右边

\frac{9}{25} h - 12 = - \frac{3}{5} k

将

12

到右边

\frac{9}{25} h = - \frac{3}{5} k + 12

在两边乘以

25

9 h = - 15 k + 300

两边除以

9

h = \frac{5 ( - k + 20 )}{3}

3(4x+1)=-3(3x-2)+4x

3 (4 x + 1) = - 3 (3 x - 2) + 4 x

(4x-2)/8-(5x-3)/4 =(2x-1)/6

\frac{4 x - 2}{8} - \frac{5 x - 3}{4} = \frac{2 x - 1}{6}

x + 4 = 3 x - 10

5 (0.3) + 2 y = 20

solvefor x,z=xy+10

so l v e f or x, z = x y + 10
