0.5(4x-2)=3.60.5(4x-2)=3.60.5(4x-2)=3.62x-1=3.62x=3.6+12x=4.6x=4.6÷2x=2.3即4x-2=7.2,移项的4x=9.2,解之得x=2.
0.5(4x-2)=3.6
0.5(4x-2)=3.6
0.5(4x-2)=3.6
2x-1=3.6
2x=3.6+1
2x=4.6
x=4.6÷2
x=2.3
即4x-2=7.2,移项的4x=9.2,解之得x=2.3
展开得到2x-1=3.6 2x=4.6 x=2.3
3.2+x=4.6 x-2.08=5.76 1.2x=0.84 3x+0.5x=4.2 4x-2.16=1.2 x-0.2x=16 2x-4*2.5=3.6 x除以5.4=0.26
3x+0.5x=4.2 4x-2.16=1.2 x-0.2x=16 2x-4x[这个x是乘】2.5=3.6 3x+5x=168 怎么解
