3x+24=9x

解答

3 x + 24 = 9 x

x = 4

求解步骤

3 x + 24 = 9 x

将

24

到右边

3 x = 9 x - 24

将

9 x

para o lado esquerdo

- 6 x = - 24

两边除以

- 6

x = 4

\frac{x + 2}{3} = \frac{3 x + 4}{5}

\frac{( - 2 x + 1 ) \cdot 3 - 10}{2} = 3 (x + 1) - (\frac{12}{6}) (- x + 2)

27.93 = (x \cdot 0.3) 9.8

3 (4 - 2 x) = - x + 1

so l v e f or M, D = \frac{M}{V}
