solvefor x,428x x/y =12.24

解答

求解

x, 428 x \frac{x}{y} = 12.24

解答

x = \frac{3 17 y}{5 214}, x = - \frac{3 17 y}{5 214}; y \neq = 0

求解步骤

428 x \frac{x}{y} = 12.24

化简

\frac{428 x ^{2}}{y} = 12.24

在两边乘以

y

\frac{428 x ^{2} y}{y} = 12.24 y; y \neq = 0

428 x^{2} = 12.24 y; y \neq = 0

两边除以

428; y \neq = 0

\frac{428 x ^{2}}{428} = \frac{12.24 y}{428}; y \neq = 0

x^{2} = \frac{12.24 y}{428}; y \neq = 0

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = \frac{12.24 y}{428}, x = - \frac{12.24 y}{428}; y \neq = 0

化简

\frac{12.24 y}{428} : \frac{3 17 y}{5 214}

化简

- \frac{12.24 y}{428} : - \frac{3 17 y}{5 214}

x = \frac{3 17 y}{5 214}, x = - \frac{3 17 y}{5 214}; y \neq = 0
