Question

Find the value of x and y. Quadrilateral ABCD is a parallelogram.

Answer 1

diagram?

Answer 2

DC - X+2y
DA- 2x - 3y
AB- 25
CB- 15

Answer 3

AB + CD because Opposite sides of a parallelogram are congruent,

so x + 2y = 25

and DA = CB for the same reason, so

2x - 3y = 15

So your two pairs of equations are
x + 2y = 25
2x - 3y = 15

Now, you can solve this pair?
