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 ...
Solve the system of equations by elimination. 3x - 5y = -12 6x + 8y = -24 a) x = 0, y = -4 (0, -4) b) x = 4, y = 0 (4, 0) c) x = -4, y = 0 (-4, 0) d) x = 0, y = 4 (0, 4) Solve a system of equations by elimination. 2x - y = 8...
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. 3x-y=26 (1)-2x-y=-24 (2)解 (2)-(-2/3)×(1)代替(2)，原方程组化为 3x-y=26 (1)(-5/3)y=-20/3 (2)解得y...
