3本故事书加4本画册等于221元,1本画册减1本故事书等于8元,故事书多少钱1个回答2024-01-27 07:51
如果学过方程的话
设一本故事书x元,一本画册y元
列出方程组
3x+4y=221
y-x=8
下面一个式子左右两边都乘以3,与上面一个式子左边加左边,右边加右边,得3x+4y+3y-3x=221+8*3
即7y=245,y=35
又因为y-x=8,所以x=27
如果没有学过方程的话,可以这么想
1本画册减1本故事书等于8元,那么
4本画册减4本故事书等于8*4=32元
这根
3本故事书加4本画册
之间差了7本故事书的钱,所以中间的差价221-32=189应该是7本故事书的钱
那么每一本故事书就是189除以7等于27元
再想到1本画册减1本故事书等于8元,所以画册比故事书多8元值35元
