解一元一次方程的基本方法是五步法:即去分母、去括号、移项、合并、把系数化为1.然而有些方程不一定要按常规的方法去解.一、巧化系数为1例1解方程-0.25x=3解两边同乘以-4得x=-12二、巧凑整例2解方程(11/7)x+(2/5)=(4/7)x-3/5解移项得(11/7)x-(4/7)x=-3/5-2/5 The basic method of solving a linear equation is a five-step method: that is, go to the denominator, remove the parentheses, move items, and merge the coefficients into 1. However, some equations do not have to be solved according to the conventional method. Example 1 Solve the equation -0.25x = 3 Solve both sides of the same multiplied by -4 x = -12 Second, the cohesion of the entire solution 2 Solution equation (11/7) x + (2/5) = (4/7) x-3 / 5 The solution is (11/7) x- (4/7) x = -3 / 5-2 / 5
