The answer is B)x+y=y+x.
This is just changing the order of the numbers to get the same equation....\
So for example if I have 2+7 and I use the property of addition It would give me 2+7=7+2.

Hey there!
2x + 1 < 5
SUBTRACT 1 to BOTH SIDES
2x + 1 - 1 < 5 - 1 
SIMPLIFY IT! 
2x < 5 - 1 
2x < 4
DIVIDE 2 to BOTH SIDES 
2x/2 < 4/2 
SIMPLIFY IT! 
x < 4/2
x < 2
Therefore, your answer is: x < 2 
(The graph is down below)
Good luck on your assignment & enjoy your day!
