use elimination to solve each system of equations 例子:X- Y= 1 X + Y= 3 and 3x-y=26 -2x-y= -24 答案 利用消元法求解每个方程组1.x-y=1 (1)x+y=3 (2)解 (2)-1×(1)代替(2),原方程组化为x-y=1 (1)2y=2 (2)解得y=1代入(1)得x-1=1,x=2,故方程组的解为x=2,y=1.2...
Elimination Method: In the elimination method, when two equations are given and we have to find the value of the variables such as {eq}x{\text{ and }}y {/eq}, then the elimination method is used to cancel out one term and find the value of another term. In this, we p...
When solving a system of equations, one can make use of the elimination method. The elimination method requires eliminating other variables first such that a solution could be found on that one remaining variable. This value is then substituted to that variable on one of the equations in ...
