Question

ABCD is a parallelogram. If AB = 2x - y, CD = 7, BC = x + y , AD = 2 find x and y.

Answer 1

it is a parallelogram, hence AB = CD and BC = AD
plug the given information in, what do you get for AB = CD?

Answer 2

2x - y =7

Answer 3

and BC = AD is x + y =2

Answer 4

did u get ur answer?

Answer 5

how about AB = CD?

Answer 6

I don't know how to get the answer, like do I make both equations equal to each other or solve one at a time?

Answer 7

I am guiding you, just answer my questions, AB = CD gives you what??

Answer 8

2x - y = 7

Answer 9

Ok
now you have 2 equations
x+y = 2
2x-y = 7
--------------
add them together, what do you get?

Answer 10

3x = 9
