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? 我们如果将方程组以一个新的形式表达...

A linear system is a system of linear equations. In this section we will explore the case in which we have two equations in two variables, a “2 by 2” for short. The method of elimination is a nice way to solve these systems. Substitution works fine, too. For elimination, rewrite...

So, the solution of this system of linear equations is x=0, y =2. When solving systems by graphing, there are three possible outcomes: we could have exactly one solution, as seen in the previous example; we could have no solutions at all; or we could have infinitely many solutions. ...
