解答

展开

- 8 - 3 (w + 13 = 4 w + 11) - 7 w

- 3 w - 47 = - 3 w - 33

求解步骤

- 8 - 3 (w + 13 = 4 w + 11) - 7 w

= - 8 - 3 (w + 13 \cdot 4 = w + 11) - 7 w

乘开

- 3 (w + 13 = 4 w + 11) : - 3 w - 39 = 4 w - 33

- 8 - 3 w - 39 = 4 w - 33 - 7 w

化简

- 8 - 3 w - 39 = 4 w - 33 - 7 w : - 3 w - 47 = - 3 w - 33

- 3 w - 47 = - 3 w - 33
