Question

ABCD is a parallelogram. Use a system to find x and y if AB=6x+30, BC=2x-5, CD=2y-10, and AD=y-35. Please help!

Answer 1

I understand that opposite sides are congruent, but I have no perimeter given. So, it's confusing.

Answer 2

Hey so here's a sketch of what's going on.

Answer 3

That's the first thing I did

Answer 4

Since the opposite sides are congruent like you said we can write:

6x + 30 = 2y - 10

and

y - 35 = 2x - 5

Answer 5

Yes, because opposite sides are congruent

Answer 6

Now try solving each side for Y.

Answer 7

Are you familiar with solving systems of equations?
