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

解答

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

解答

x = 1

求解步骤

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

消掉

\frac{2 ( x - 1 )}{4} : \frac{x - 1}{2}

\frac{x - 1}{2} - \frac{3 ( - 2 x + 1 )}{6} = \frac{5 x - 1}{8}

消掉

\frac{3 ( - 2 x + 1 )}{6} : \frac{- 2 x + 1}{2}

\frac{x - 1}{2} - \frac{- 2 x + 1}{2} = \frac{5 x - 1}{8}

乘以最小公倍数

4 (x - 1) - 4 (- 2 x + 1) = 5 x - 1

展开

4 (x - 1) - 4 (- 2 x + 1) : 12 x - 8

12 x - 8 = 5 x - 1

将

8

到右边

12 x = 5 x + 7

将

5 x

para o lado esquerdo

7 x = 7

两边除以

-(6x-2)=-(6x-3)

- (6 x - 2) = - (6 x - 3)

8x-(1-5x)=13x-3(2x-11)

8 x - (1 - 5 x) = 13 x - 3 (2 x - 11)

solvefor q,p= q/4-r

so l v e f or q, p = \frac{q}{4} - r

6(2x-6)=-7(-2x+4)

6 (2 x - 6) = - 7 (- 2 x + 4)

solvefor c,x^2+y^2+c=0

so l v e f or c, x^{2} + y^{2} + c = 0
