x - y = 5
2x = 2y + 10
The system of equations above has how many solutions?
Choose the most appropriate option
A) Infinitely many  B) Exactly one  C) Exactly two  D) Exactly three  E) None
x-y=5 ---------------1   2x=2y+10 ---------------2   Divide equation 2 by 2:   2x/2=(2y+10)/2   x=y+5   x-y=5----------------3   Equation 1 and 3 are equal and thus have infinitely many solutions:   x-y=5   x=5, y=0   x=6, y=1   x=7, y=2   Infinitely manyns:Infinitely many
