solvefor Q,3g^3+m=5Qd

解答

求解

Q, 3 g^{3} + m = 5 Q d

Q = \frac{3 g ^{3} + m}{5 d}; d \neq = 0

求解步骤

3 g^{3} + m = 5 Q d

交换两边

5 Q d = 3 g^{3} + m

两边除以

5 d; d \neq = 0

Q = \frac{3 g ^{3} + m}{5 d}; d \neq = 0

so l v e f or x, x - 3 y + 2 z = - 3

f (x) (g (x)) = g (x) (f (x))

\frac{4}{3} (15 - 21 x) + x = 74

so l v e f or x, 3 x + 2 y - z = 8

so l v e f or C, S = C + RC
