1000011/200+x3/50 =1990

解答

10000 \cdot \frac{11}{200} + x \cdot \frac{3}{50} = 1990

x = 24000

求解步骤

10000 \cdot \frac{11}{200} + x \frac{3}{50} = 1990

将

10000 \cdot \frac{11}{200}

到右边

x \frac{3}{50} = 1440

在两边乘以

50

3 x = 72000

两边除以

3

x = 24000

so l v e f or x, \frac{3}{5} x + \frac{7}{8} y = \frac{12}{3}

so l v e f or x, y + \frac{1}{3} x = 2

so l v e f or x, y + \frac{4}{2} = x (2)

\frac{t + 31}{9} = 6

so l v e f or y, y + z = 8
