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

解答

\frac{2 x}{3} + \frac{1}{2} = \frac{x}{2} - \frac{1}{3}

x = - 5

求解步骤

\frac{2 x}{3} + \frac{1}{2} = \frac{x}{2} - \frac{1}{3}

将

\frac{x}{2}

para o lado esquerdo

\frac{x + 3}{6} = - \frac{1}{3}

在两边乘以

6

x + 3 = - 2

将

3

到右边

x = - 5

so l v e f or x, y + 3 = \frac{1}{2} (x + 2)

so l v e f or T, T (\frac{x}{y}) = (\frac{x ^{2}}{y ^{2}})

so l v e f or x, 7 x + y = - 4

so l v e f or x, 7 x + y = - 2

12 = - 4 (6 x - 3)
