x-(2x/3-2)-{0.4[x-(2x/3-2)]+3}=6 不要看错啊,我知道答案是39
x-(2x/3-2)-{0.4[x-(2x/3-2)] 3}=6 解方程,x-(2x/3-2)-{0.4[x-(2x/3-2)]+3}=6 不要看错啊,我知道答案是39
x-(2x/3-2)-{0.4[x-(2x/3-2)]+3}=6
(x-2x/3+2)-0.4(x-2x/3-2)-3=6
(1-0.4)(x-2x/3-2)=6+3
0.6(x/3-2)=9
x/3-2=9÷0.6=15
x/3=15+2=17
x/3=17÷1/3
x=51
解由x-(2x/3-2)-{0.4[x-(2x/3-2)] 3}=6
得x-(2x/3-2)-{0.4(x-2x/3+2) 3}=6
即x-(2x/3-2)-{0.4(x/3+2) 3}=6
即x-(2x/3-2)-{2/5(x+6) }=6
即x-2x/3+2-2x/5-12/5 =6
即x/3-2x/5-12/5 =4
即5x/15-6x/15=4+12/5
即-x/15=20/5+12/5
即-x/15=32/5
两边乘以-15
即x=32×(-3)
即x=-96
