解:①3.85+1.5x=6.1,
3.85+1.5x-3.85=6.1-3.85,
1.5x=2.25,
1.5x÷1.5=2.25÷1.5,
x=1.5;
②x÷1.44=0.4,
x÷1.44×1.44=0.4×1.44,
x=0.576;
③2(x+5)=13.6,
2(x+5)÷2=13.6÷2,
x+5=6.8,
x+5-5=6.8-5,
x=1.8;
④x-0.36x=16,
0.64x=16,
0.64x÷0.64=16÷0.64,
x=25.
分析:①根據(jù)等式的性質,兩邊減去3.85,再同除以1.5即可;
②再根據(jù)等式的性質,兩邊同乘1.44即可;
③根據(jù)等式的性質,兩邊同除以2,得x+5=6.8,再根據(jù)等式的性質,兩邊同減去5即可;
④先求出x-0.36x=0.64x,根據(jù)等式的性質,再同除以0.64即可.
點評:此題考查了根據(jù)等式的性質解方程,即等式兩邊同加、同減、同乘或同除以一個數(shù)(0除外),等式的左右兩邊仍相等;注意等號上下要對齊.
