Answer 2

use the triangle law of vectors to find vector OR in terms of x and y.

you can find all the required vector in terms of the vertical vector x and the horizontal vector OR.

for example, to go from O to point P,
we need to go two units up: so 2x
and two units left: so -OR

Answer 3

i'm also getting 2x-y but the book answer says it is 3x-y

Answer 4

OR is not y
use the triangle law to find OR in terms of x and y

Answer 5

i'm not sure how to do...can u show me ur working pls

Answer 6

shift the tail of vector X to the head of vector OR, but keep it paralell to the original X

Answer 7

now,
Y=OR+X

Answer 8

because to get to the tip of Y, you have to go along OR and then along X

Answer 9

so, rearrange
OR=y-x

Answer 10

oh i get it to find op,\[OP=2x+x-y\]\[op=3x-y\]
