[3x(11-5)-7.4]-(6x-4)=0

解答

[3 x (11 - 5) - 7.4] - (6 x - 4) = 0

解答

x = 0.28333 \dots

求解步骤

[3 x (11 - 5) - 7.4] - (6 x - 4) = 0

去除括号:

(a) = a

3 x (11 - 5) - 7.4 - (6 x - 4) = 0

3 x (11 - 5) = 18 x

18 x - 7.4 - (6 x - 4) = 0

将

7.4

到右边

18 x - (6 x - 4) = 7.4

展开

18 x - (6 x - 4) : 12 x + 4

12 x + 4 = 7.4

将

4

到右边

12 x = 3.4

两边除以

12

x = 0.28333 \dots

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

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

2 q + 6 = 12

333/1000 =1-(x/(13363))

\frac{333}{1000} = 1 - (\frac{x}{13363})

solvefor d,a^2-a-18=3d*a^{-1}

so l v e f or d, a^{2} - a - 18 = 3 d \cdot a^{- 1}

f = (8)^{\frac{5}{3}}
