solvefor A,AX+BX=C

解答

求解

A, A X + BX = C

A = \frac{C - XB}{X}; X \neq = 0

求解步骤

A X + BX = C

将

BX

到右边

A X = C - BX

两边除以

X; X \neq = 0

A = \frac{C - XB}{X}; X \neq = 0

\frac{3}{5} x + \frac{2}{3} + x = \frac{1}{2} - \frac{1}{5} x

so l v e f or d, \frac{p ^{2}}{4} + d = 4

(2 x - 1) 0.5 - 4 (x + 2) = 1

2 (x + 1) + 3 (x - 2) = x + 3

so l v e f or x, p x + 17 = 12
