solvefor x,2 1/5 (x-16/25)=0.33

解答

求解

x, 2 \frac{1}{5} (x - \frac{16}{25}) = 0.33

解答

x = 1.465

求解步骤

2 \cdot \frac{1}{5} (x - \frac{16}{25}) = 0.33

化简

2 \cdot \frac{1}{5} : \frac{2}{5}

\frac{2}{5} (x - \frac{16}{25}) = 0.33

在两边乘以

5

2 (x - \frac{16}{25}) = 1.65

两边除以

2

x - \frac{16}{25} = 0.825

将

\frac{16}{25}

到右边

x = 1.465

3/7 y+1/2 = 1/7

\frac{3}{7} y + \frac{1}{2} = \frac{1}{7}

2 z = 0

x - (- 2) = 2

12z-9-10z+3-8z=z-9+2z+10-10z

12 z - 9 - 10 z + 3 - 8 z = z - 9 + 2 z + 10 - 10 z
