展开

- 1 (y - x = 10)

- y + x = 10

求解步骤

- 1 \cdot (y - x = 10)

= - 1 \cdot (y - 10 = x)

使用分配律:

a (b - c) = ab - a c

a = - 1, b = y, c = x = 10

- 1 \cdot y - (- 1) x = 10

使用加减运算法则

- (- a) = a

- 1 \cdot y + 1 \cdot x = 10

乘开

- 1 \cdot y + 1 \cdot x : - y + x

- y + x = 10

\frac{d}{d y} ((x) (6 x + ln (6 y)))

e x p an d e^{4 x} \cdot 4 (x^{2} + 1) - 2 x e^{4 x}

e x p an d H^{2} + (0.1 t + 1)^{2}

e x p an d 12 (5 (0.675) - 4.5 = 36)

e x p an d (x y + 2 x y ln^{2} (y) + y ln (y)) d x
