x-9/10 x=(-131)/(100)

解答

x - \frac{9}{10} x = \frac{- 131}{100}

x = - \frac{131}{10}

十进制

x = - 13.1

求解步骤

x - \frac{9}{10} x = \frac{- 131}{100}

在两边乘以

10

x = - \frac{131}{10}

so l v e f or x, 386.85 = 3.9 x^{102} g

so l v e f or x, p + \frac{2}{6} - 11 - \frac{p}{3} - \frac{1}{4} = 3 x - \frac{4}{12}

h = 0.033 (2.5 + 2 h) \cdot 25

so l v e f or x, 2 y = 3 - x

p (- 2) = - 815 + (- 2 p) + 513
