方程x-0.18x=32.8怎么解
方程x-0.18x=32.8怎么解

方程x-0.18x=32.8怎么解
x-0.18x=32.8
(1-0.18)x=32.8
0.82x=32.8
x=32.8÷0.82
x=40

x(1-0.18)=32.8
x=32.8/(1-0.18)
x=40

x-0.18x=32.8
解:x(1-0.18)=32.8
0.82x=32.8
x=40

x-0.18x=32.8
(1-0.18)x=32.8
0.82x=32.8
x=40

x-0.18x=32.8
即x(1-0.18)=32.8
即0.82x=32.8
所以x=40

X-0.18X=32.8
合并同类项
0.82X=32.8
系数化为一
X=40

x-0.18x=32.8
(1-0.18)x=32.8
x=32.8/(1-0.18)
x=40

X=40

(1-0.18)X=32.8
0.82X=32.8
X=32.8*0.82
X=40

0.82x=32.8 x=32.8/0.82=40

x-0.18x=32.8→100x-18x=3200→82x=3280→x=3280/82=40

x-0.18x=32.8
0.82x=32.8
x=40

解:(1-0.18)x=32.8
0.82x=32.8
x=40

X=40
