88-71=17 is too much. In fact, it is three yuan. For example, in the linear equation model, 66 is regarded as 6*10 6*1. How to solve a similar problem like x minus 5/18x equals 7/16 to find x

x-5x/18=7/ 16

Calculate the left side first, and get

13x/18=7/16

Then multiply both sides by 18/13 at the same time, so that the coefficient in front of x is 1, you can find x

x=(7/16)×(18/13)=63/104
