solvefor s,-77=11u+99

解答

求解

s, - 77 = 11 u + 99

对所有 s 为真; - 77 = 11 u + 99

求解步骤

- 77 = 11 u + 99

两侧相等

对所有 s 为真; - 77 = 11 u + 99

\frac{7}{3} x + \frac{6}{3} x = \frac{6}{2} x + \frac{3}{2} x + 8

x = lo g_{3} (53)

(3 x + 4) - (2 x + 9) = 15

(x + 5) (x + 2) - 3 (4 x - 3) = (5 - x)^{2}

so l v e f or x, y + x + 4 = 0
