二元一次方程组的解是指能同时满足方程组中两个方程的一对未知数的值,即当已知某一对数值是二元一次方程组的解时≯把它1『1代人方程组,两个方程一定同时成立,由此可求得原方程组中的待定字{擘的值,下面举例说明. The solution of the binary system of primary equations is the value of a pair of unknowns that can simultaneously satisfy the two equations in the system of equations. That is, when a certain logarithmic value is known to be a solution to a binary equation system, The equations, the two equations must be established at the same time, which can be obtained in the original equations of the pending word {擘 value, the following example.
