(3x)/4+3=(7x)/(10)

解答

\frac{3 x}{4} + 3 = \frac{7 x}{10}

x = - 60

求解步骤

\frac{3 x}{4} + 3 = \frac{7 x}{10}

乘以最小公倍数

15 x + 60 = 14 x

将

60

到右边

15 x = 14 x - 60

将

14 x

para o lado esquerdo

x = - 60

so l v e f or x, p = 4 a^{3} b + 10 a^{2} b^{2}

\frac{11 x - 1}{16} + \frac{x + 1}{4} = x

- 9 + x = - 1

29 = - 14 x + 1

so l v e f or p, 9 p + 15 q = 66
