solvefor a,c=(ad)/(a+12)

解答

求解

a, c = \frac{a d}{a + 12}

解答

a = - \frac{12 c}{c - d}; c \neq = d

求解步骤

c = \frac{a d}{a + 12}

在两边乘以

a + 12

c (a + 12) = a d

展开

c (a + 12) : a c + 12 c

a c + 12 c = a d

将

12 c

到右边

a c = a d - 12 c

将

a d

para o lado esquerdo

a c - a d = - 12 c

分解

a c - a d : a (c - d)

a (c - d) = - 12 c

两边除以

c - d; c \neq = d

a = - \frac{12 c}{c - d}; c \neq = d

1+9/(x-8)=(2x)/(x-8)

1 + \frac{9}{x - 8} = \frac{2 x}{x - 8}

3(x+4)+(-3)/(x+4)=8

3 (x + 4) + \frac{- 3}{x + 4} = 8

\frac{1}{x ^{2} - 2} = 0

solvefor C,T= Q/(mCe)

so l v e f or C, T = \frac{Q}{m C e}

\frac{3}{4} = \frac{1.83}{x}
