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...
.Okay, let's get started on the solution tothis system.The Method of Elimination tells us that we first need to multiply one or both of the equations by constants so that one of the variables has the same coefficient but with opposite signs and then add the two equations.For this system...
Use the substitution or elimination method to solve each system of equations. State whether it is an inconsistent system or has infinitely many solutions. If a system has infinitely many solutions, write the solution set with y arbitrary.2x+y+z=3x+2y-z=33x-y+z=5 相关知识点: 试题来源:...
