分析:(1)根據(jù)圖示列出方程x×1.5+2x=1.05,先根據(jù)乘法分配律改寫成(1.5+2)x=1.05,即3.5x=1.05,再根據(jù)等式的性質(zhì),兩邊同除以3.5即可;
(2)根據(jù)圖示列出方程(y+3.2)×1.6=8.8,即1.6y+5.12=8.8,根據(jù)等式的性質(zhì),兩邊同減去5.12,再同除以1.6.
解答:解:(1)x×1.5+2x=1.05,
(1.5+2)x=1.05,
3.5x=1.05,
3.5x÷3.5=1.05÷3.5,
x=0.3;
(2)(y+3.2)×1.6=8.8,
1.6y+3.2×1.6=8.8,
1.6y+5.12=8.8,
1.6y+5.12-5.12=8.8-5.12,
1.6y=3.68,
1.6y÷1.6=3.68÷1.6,
y=2.3.
點評:此題考查了根據(jù)等式的性質(zhì)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.
