(99.5)/(x+22)=63.2

解答

\frac{99.5}{x + 22} = 63.2

解答

x = - \frac{12909}{632}

+1

十进制

x = - 20.42563 \dots

求解步骤

\frac{99.5}{x + 22} = 63.2

在两边乘以

x + 22

99.5 = 63.2 (x + 22)

交换两边

63.2 (x + 22) = 99.5

在两边乘以

10

632 (x + 22) = 995

两边除以

632

x + 22 = \frac{995}{632}

将

22

到右边

x = - \frac{12909}{632}

验证解

找到无定义的点（奇点）:

x = - 22

将不在定义域的点与解相综合:

x = - \frac{12909}{632}

2=(50)/((44+r))

2 = \frac{50}{( 44 + r )}

solvefor x,z=y+m/x

so l v e f or x, z = y + \frac{m}{x}

\frac{4}{x} + 1 = x - 3

\frac{5}{4} = \frac{6}{x}

(3y)/(y+2)=6-6/(y+2)

\frac{3 y}{y + 2} = 6 - \frac{6}{y + 2}
