x=2 a/t ,y= a/(t^2)

解答

x = 2 \frac{a}{t}, y = \frac{a}{t ^{2}}

2 t^{2}

求解步骤

给定

x = 2 \frac{a}{t}, y = \frac{a}{t ^{2}}

找到

x \circ y

x \circ y = (x) ((y) (t))

y = \frac{a}{t ^{2}}

= (x) (\frac{a}{t ^{2}})

(x) (\frac{a}{t ^{2}}) : 2 t^{2}

= 2 t^{2}

6 x - 3 y = 0, x + y = - 6

8 x + 7 y = 38, 3 x - 5 y = 10

4 x + 6 y = 15, 6 x - 8 y = 14

x + y = 11, y + 2 = \frac{1}{8} \cdot (10 y + x) \cdot 1

25 x + 10 y = 50, - 6 x + 10 y = 24
