In order to solve the system of equations with the three variable, it should be given with three equations, that may r may not contain these three variables. But will have at least one variable, then we need to use the substitution method to solve then...
方程组(system of equations),一般有n个方程和n个未知数。对于线性方程组(system of linear equations),即未知数的幂都是1的方程组,通常,在中学阶段,我们会一般使用联立求解的方法求解出未知数(比如说x,或者y等),那么有没有什么其他方法也能求解出线性方程组呢?
