solvefor a, x/a+b=c

解答

求解

a, \frac{x}{a} + b = c

解答

a = \frac{x}{c - b}; c - b \neq = 0

求解步骤

\frac{x}{a} + b = c

将

b

到右边

\frac{x}{a} = c - b

在两边乘以

a

x = c a - ba

交换两边

c a - ba = x

分解

c a - ba : a (c - b)

a (c - b) = x

两边除以

c - b; c - b \neq = 0

a = \frac{x}{c - b}; c - b \neq = 0

流行的例子

3/(x-2)= 2/(x-3)

\frac{3}{x - 2} = \frac{2}{x - 3}

\frac{10}{7} = \frac{50}{x}

x - 2 = \frac{3}{x}

x/(x-2)-5/(x+1)=1

\frac{x}{x - 2} - \frac{5}{x + 1} = 1

3=(a-(-3))/(5-a)

3 = \frac{a - ( - 3 )}{5 - a}
