solvefor x,12x+3y=12

解答

求解

x, 12 x + 3 y = 12

x = \frac{4 - y}{4}

求解步骤

12 x + 3 y = 12

将

3 y

到右边

12 x = 12 - 3 y

两边除以

12

x = \frac{4 - y}{4}

so l v e f or x, x - x y = 1

so l v e f or x, 144 x + 1000 y + 44 z = 376

so l v e f or W, 7 = L W

so l v e f or f, f (x^{- 1}) = e^{x}

f = lo g_{3} (1)
