solvefor x,3xy+4=1

解答

求解

x, 3 x y + 4 = 1

x = - \frac{1}{y}; y \neq = 0

求解步骤

3 x y + 4 = 1

将

4

到右边

3 x y = - 3

两边除以

3 y; y \neq = 0

x = - \frac{1}{y}; y \neq = 0

f (y), y = - \frac{1}{8}

so l v e f or x, \frac{( x + y )}{6} - \frac{( y - x )}{3} = \frac{7}{24}

c = \frac{8 ^{3}}{( 2 ^{3} )}

(b - b) \cdot x^{2} + (c - a) \cdot x + (a - b) = 0

6 (x^{2} + 1) - (2 x - 4) (3 x + 2) = 3 (5 x + 21)
