solvefor x,x-7=7y

解答

求解

x, x - 7 = 7 y

x = 7 y + 7

求解步骤

x - 7 = 7 y

将

7

到右边

x = 7 y + 7

so l v e f or x, y^{0.12} = 6 x + 3 y

so l v e f or x, 5 x + 3 y = 95

\frac{x}{2 + 1} = x

3 + \frac{x}{4} = \frac{1}{2} \cdot (4 - \frac{x}{3}) - \frac{5}{6} + \frac{1}{3} \cdot (11 - \frac{x}{2})

\frac{x}{3} + x + \frac{1}{4} = 9
