3(x+6)-2(x+7)=4-x

解答

3 (x + 6) - 2 (x + 7) = 4 - x

x = 0

求解步骤

3 (x + 6) - 2 (x + 7) = 4 - x

展开

3 (x + 6) - 2 (x + 7) : x + 4

x + 4 = 4 - x

将

4

到右边

x = - x

将

x

para o lado esquerdo

2 x = 0

两边除以

2

x = 0

\frac{1}{3} [2 + \frac{1}{5} (4 z - 1)] = \frac{3}{4} z - \frac{1}{3}

2 (x + 5) - 3 (5 - x) = 10

- 6 - 5 D + 24 = 2 D + 9 - 7 D

x (4 - 2) + 9 = 3 (5 - x) + 3 x

so l v e f or x, 2 y = 1 + x y^{3}
