I can do the application questions, which are the solutions to the equations listed separately. For example, the two sides of the equation don't form the same number at the same time, and usually only multiply on the left There are also questions like 1.5 (80-x) = 2 / 3 (90-x) with subtracted numbers, I want the method of solving equations and typical examples, It's a one-dimensional equation!
