解答

展开

- 3 (4 x + 3) + 4 (6 x + 1 = 43)

12 x - 5 = 43

求解步骤

- 3 (4 x + 3) + 4 (6 x + 1 = 43)

= - 3 (4 x + 3) + 4 (6 x + 1 \cdot 43 =)

乘开

- 3 (4 x + 3) : - 12 x - 9

= - 12 x - 9 + 4 (6 x + 1 = 43)

乘开

4 (6 x + 1 = 43) : 24 x + 4 = 43

- 12 x - 9 + 24 x + 4 = 43

乘开

- 12 x - 9 + 24 x + 4 : 12 x - 5

12 x - 5 = 43
