5x1y2 20x4y8 Enter your answer as an ordered pair For exampl

5x+1y=2

-20x-4y=-8

Enter your answer as an ordered pair. For example, if your answer is x=2, y=-3, then enter (2,-3). If there are infinitely many solutions, use x as the parameter, and enter y as a function of x. For example, the solution for x+y=1, 2x+2y=2 is (x,1-x)

Solution

5x+1y=2 ----(1)

-20x-4y=-8 ----(2)

Multiply equtaion by 4: 20x +4y = 8

-20x -4y =-8

subtract the two equations

--------------------------------

0 =0

There aree infinte solutions; So we can write : y = 2-5x

Ordered pair: (x, 2 -5x)
