6.8-1.2X=6.5
6.8-1.2X=6.5
6.8-1.2x=6.5
1.2x=6.8-6.5
1.2x=0.3

希望可以帮到你.
1.2x=0.3

x=0.25
1.2x=6.8-6.5
1.2x=0.3
x=0.25
0.3=1.2x,x=1/4
-1.2x =-0.3 x =0.25
6.8-1.2X=6.5
-1.2X=-0.3
X=0.25
6.8-1.2X=6.5
解方程:6x+8.3=11.18-2.5x=5.5.x+6.5x=1.2
13x-6.8x+x=46.
解方程 6.5x-3.8x=27 6x+8x=448 3.4x-5.1X4=6.8X和x不一样,X是乘号x是字母.
6.8x-x=20.3
6.5x-4.5x=93.6-6.5x-3.5x
6.5x-x=10.
6.5x+x=1.5
3.6x-x=6.5
1.2x=x+20
1.2X-30=X
1.2x-x=0.
x-1.2x=9.6
x-40%x=1.2
x+x=() x*x=() x-0.8x=() 1.2*2y=()
0.5x+1.2-4x+6.5x=4.8 (12-2x)+(3.2x-4.8)=24 (2x+5)‐(20‐3x)=175 25-2(30‐20x)=16
3x-1.2x=363x-1.2x=363x-1.2x=363x-1.2x=363x-1.2x=36
解下列方程 x+4.8=7.2 x-6.5=3.2 x÷8=0.4 6x+18=48 3(x+2.1)=10.5 12x-9x=8.7解下列方程 3.8+x=6.3 x-7.9=2.6 2.5x=14 x÷3=1.2 3.4x-48=26.8 2x-97=34.2 42x+25x=134 13(x+5
