[((f-0.0075))/(0.0075)]*(12/3)=0

解答

[\frac{( f - 0.0075 )}{0.0075}] \cdot (\frac{12}{3}) = 0

解答

f = \frac{0.03}{4}

+1

十进制

f = 0.0075

求解步骤

[\frac{( f - 0.0075 )}{0.0075}] (\frac{12}{3}) = 0

展开

(\frac{f - 0.0075}{0.0075}) (\frac{12}{3}) : \frac{4 f}{0.0075} - \frac{0.03}{0.0075}

\frac{4 f}{0.0075} - \frac{0.03}{0.0075} = 0

在两边乘以

0.0075

4 f - 0.03 = 0

将

0.03

到右边

4 f = 0.03

两边除以

4

f = \frac{0.03}{4}

solvefor x,x-y=19

so l v e f or x, x - y = 19

(x-5)/3 =(x-3)/5

\frac{x - 5}{3} = \frac{x - 3}{5}

6 x - 12 = 8 x + 5

solvefor x,2x-y= 3/2

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

543 + x = 5
