solvefor a,z=ma+ba

解答

求解

a, z = ma + ba

a = \frac{z}{m + b}; m \neq = - b

求解步骤

z = ma + ba

交换两边

ma + ba = z

分解

ma + ba : a (m + b)

a (m + b) = z

两边除以

m + b; m \neq = - b

a = \frac{z}{m + b}; m \neq = - b

\frac{h}{- 3} + 7 = 8

2 (x - 2)^{2} = (x + 1) (x - 1) + x (x - 2)

so l v e f or D, D - 4 G = \frac{1}{4} b

2 (- 2 x - 5) - 3 (1 - 4 x) = 7 (x + 1)

3 - 2 y = 20 + 1
