x - y =2
2x = 2y + 4
The system of equations above has how many solutions?
Select the correct option:
A) None  B) Exactly one  C) Exactly two  D) Infinitely many  E) Exactly three
x-y=2 ---------------1   2x=2y+4 ---------------2   Infinitely manyivide equation 2 by 2:   2x/2=(2y+4)/2   x=y+2   x-y=2----------------3   Equation 1 and 3 are equal and thus have infinitely many solutions:   x-y=2   x=4, y=2   x=6, y=4   x=7, y=5   Ans:Infinitely many
<result>D</result>
x - y =2
2x = 2y + 4
