3+x/4 = 1/2(4-x/3)-5/6+1/3(11-x/2)

解答

3 + \frac{x}{4} = \frac{1}{2} \cdot (4 - \frac{x}{3}) - \frac{5}{6} + \frac{1}{3} \cdot (11 - \frac{x}{2})

解答

x = \frac{22}{7}

+1

十进制

x = 3.14285 \dots

求解步骤

3 + \frac{x}{4} = \frac{1}{2} (4 - \frac{x}{3}) - \frac{5}{6} + \frac{1}{3} (11 - \frac{x}{2})

将

3

到右边

\frac{x}{4} = - \frac{23}{6} + \frac{- x + 17}{3}

乘以最小公倍数

3 x = - 46 + 4 (- x + 17)

展开

- 46 + 4 (- x + 17) : - 4 x + 22

3 x = - 4 x + 22

将

4 x

para o lado esquerdo

7 x = 22

两边除以

7

x = \frac{22}{7}

流行的例子

\frac{x}{3} + x + \frac{1}{4} = 9

solvefor x,2x+3y=12y

so l v e f or x, 2 x + 3 y = 12 y

solvefor x,5x+7y=8

so l v e f or x, 5 x + 7 y = 8

2 x - 0.7 x = 0

4 x/5-1/6 = 9/2-2x

4 \frac{x}{5} - \frac{1}{6} = \frac{9}{2} - 2 x
