(3x+8)/2+(4x+8)/3 =(7x)/6

解答

\frac{3 x + 8}{2} + \frac{4 x + 8}{3} = \frac{7 x}{6}

解答

x = - 4

求解步骤

\frac{3 x + 8}{2} + \frac{4 x + 8}{3} = \frac{7 x}{6}

乘以最小公倍数

3 (3 x + 8) + 2 (4 x + 8) = 7 x

展开

3 (3 x + 8) + 2 (4 x + 8) : 17 x + 40

17 x + 40 = 7 x

将

40

到右边

17 x = 7 x - 40

将

7 x

para o lado esquerdo

10 x = - 40

两边除以

10

x = - 4

(2x+10)=(5x+30)2

(2 x + 10) = (5 x + 30) 2

x + 2 x - 15 = 90

y=0.118(19)+0.3248(19)+32.555

y = 0.118 (19) + 0.3248 (19) + 32.555

5 (x + 2) = 3 (x + 8)

solvefor p,ln(x)+1/3 p=0

so l v e f or p, ln (x) + \frac{1}{3} p = 0
