1/2 t-2/3 = 1/6+2/3 t

解答

\frac{1}{2} t - \frac{2}{3} = \frac{1}{6} + \frac{2}{3} t

t = - 5

求解步骤

\frac{1}{2} t - \frac{2}{3} = \frac{1}{6} + \frac{2}{3} t

将

\frac{2}{3}

到右边

\frac{1}{2} t = \frac{5}{6} + \frac{2}{3} t

将

\frac{2}{3} t

para o lado esquerdo

- \frac{1}{6} t = \frac{5}{6}

在两边乘以

- 6

t = - 5

so l v e f or a, (a + b) (a - b) = a^{2} - b^{2}

so l v e f or x, 3 x + 5 y - 15 = 0

so l v e f or x, 5 x + y = 6

3 x - 7 + 9 - 2 x = x + 2

\frac{1}{2} x + 7 - \frac{3}{4} x = 15
