(16x+3)/4-(10x+1)/6 =4(x+1)

解答

\frac{16 x + 3}{4} - \frac{10 x + 1}{6} = 4 (x + 1)

解答

x = - \frac{41}{20}

+1

十进制

x = - 2.05

求解步骤

\frac{16 x + 3}{4} - \frac{10 x + 1}{6} = 4 (x + 1)

乘以最小公倍数

3 (16 x + 3) - 2 (10 x + 1) = 48 (x + 1)

展开

3 (16 x + 3) - 2 (10 x + 1) : 28 x + 7

展开

48 (x + 1) : 48 x + 48

28 x + 7 = 48 x + 48

将

7

到右边

28 x = 48 x + 41

将

48 x

para o lado esquerdo

- 20 x = 41

两边除以

- 20

x = - \frac{41}{20}

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

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

x/2+x/6+x/(12)+x/(20)+x/(30)+x/(42)=2

\frac{x}{2} + \frac{x}{6} + \frac{x}{12} + \frac{x}{20} + \frac{x}{30} + \frac{x}{42} = 2

solvefor x,y=f+1

so l v e f or x, y = f + 1

A=(x+2)(x-7)-(x+6)(x-11)

A = (x + 2) (x - 7) - (x + 6) (x - 11)

2x+(-10)=2(3x-1)

2 x + (- 10) = 2 (3 x - 1)
