20+0.5m=30+0.25m

解答

20 + 0.5 m = 30 + 0.25 m

m = 40

求解步骤

20 + 0.5 m = 30 + 0.25 m

在两边乘以

100

2000 + 50 m = 3000 + 25 m

将

2000

到右边

50 m = 25 m + 1000

将

25 m

para o lado esquerdo

25 m = 1000

两边除以

25

m = 40

so l v e f or y, \frac{( x + y )}{4} = 5 z

5 (7 x - 6) = - 24 x + 12

so l v e f or x, y = 5 x - 6

so l v e f or x, y + x = 55

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