解答

展开

- 3 - 3 (2 x + 79 + (- 5 x + 6) - 8 (1 - 2 x) - (x - 3) = 0)

- 36 x - 243 = 0

求解步骤

- 3 - 3 (2 x + 79 + (- 5 x + 6) - 8 (1 - 2 x) - (x - 3) = 0)

= - 3 - 3 (2 x + 79 + (- 5 x + 6) - 8 (1 - 2 x) - 0 = (x - 3))

乘开

- 3 (2 x + 79 + (- 5 x + 6) - 8 (1 - 2 x) - (x - 3) = 0) : - 36 x - 240 = 0

- 3 - 36 x - 240 = 0

乘开

- 3 - 36 x - 240 : - 36 x - 243

- 36 x - 243 = 0
