Question

2x - y = 7 4x + y = -14 x - y = 4
x + 2y = 11 3x = y 2x - 2y = 8 SHOW WORK PLEASE AND THANK YOU

Answer 1

1) multiply 1 by 2 and add both equations....
x = 5, y = 3

2) put the value of y on first equation,
x = -2, y = -6

3) infinite solutions.....
such that x=4,y=0,
x= 5, y=1 and so on......

Answer 2

I DONT UNDERSTAND WHATS THE LAST ANSWER

Answer 3

actually both equations are same ..........
so x -y = 4
any value of x and y where x is greater than y by 4.......
will satisfy the equation.........

Answer 4

here there would be infinite solutions........
