1.2x-x=0.
1.2x-x=0.
1.2x-x=0.
（1.2-1）x=0.96
0.2x=0,96
x=0.96\0.2
x=4.8
不就等于0.2X=0.96，X=4.8.
x=4.8
1.2x-x=0.96
0.2x=0.96
0.2x÷0.2=0.96÷0.2
x=4.8
0.2x=0.96
x=4.8
（1.2-1）x=0.96
0.2x =0.96
x =0.96/0.2
x =4.8
1.2x-x=0.
一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X
（X+X)+(X-X)+(X*X)+(X/X)=100
16^X - 12^X -9^X = 0.求X.
(98-X)+(100-X)+X=X/0.
x-0.25x=0.
x+4.5x=0.
X-0.25x=0.
4.8x-x=0.
X-0.25x=0.
2.2x-x=0.
120X-X=0.
x-0.4x=0.
X-0.48X=0.
1.2x=x+20
1.2X-30=X
x-1.2x=9.6
x-40%x=1.2
