1, the common problems in solving equations in grade five are rush, meeting, time, engineering and so on. Solving equations is one of the important contents of fifth grade mathematics. The method of solving the equation includes removing brackets, shifting terms, merging similar terms, and converting the coefficient into 1. In the process of solving the equation, we need to pay attention to the operation order and symbol, as well as the simultaneous operation of both sides of the equation.
2. To solve practical problems with equations, it is necessary to analyze the problem first, find the relationship between the unknown and the known number, and then establish equations to solve them. When solving a problem, we should understand the practical significance of the problem, find out the key mathematical relationship and convert it into an equation. The answer to this question can be obtained by solving this equation.
3. In the pursuit problem, the relationship between distance and velocity between two objects can be solved by establishing equations. In the encounter problem, we can solve the time and place when two objects meet by establishing equations. In the problem of time, we can solve the time interval or elapsed time by establishing equations; In engineering problems, working efficiency and working time can be solved by establishing equations.
