1.2x-6=x+6解方程怎么解

1.2x-6 x+6 0.2x-6 6 0.2x 12 x 60

1.2x=9.6 x=9.6÷1.2 x=8

解:2(x+1)=6 x+1=3 x=2

如图

解:x=1.2+0.6x 0.4x=1.2 x=3

x=5/6-1/2 x=5/6-3/6 x=2/6 x=1/3

2x(x+1)=6 x+1=6÷2 x+1=3 x=3-1 x=2

1.2x+2.6=1.8x 0.6x=2.6 x=3分之13

1/2+x=5/6 x=5/6-1/2=1/3 x=1/3

3.8x+1.2x=6.5 (3.8+1.2)x=6.5 5x=6.5 x=1.3
