The ordered pair is only a solution to the first equation, so it is not a solution to the system.

2 x 10 = 20    5 x 5 = 25    20 - 25 = -5     True!

10 + 2 x 5 = 11?    False!    10 + 2 x 5 = 20

So, A and C are the correct answers!

AB=2y+1, BC=y+1,CD=7x-3,DA=3x what is x and y
sattari [20]
I attached the picture associated with this question.

Answer:
x = 2
y = 5

Explanation:
ABCD is a parallelogram. This means that each two opposite sides are equal.
This means that:
1- AB = CD
2y + 1 = 7x - 3 ...........> equation I
2- AD = BC
3x = y + 1
This can be rewritten as:
y = 3x - 1............> equation II

Substitute with equation II in equation I and solve for x as follows:
2y + 1 = 7x - 3 ...........> equation I
2(3x - 1) + 1 = 7x - 3
6x - 2 + 1 = 7x - 3
6x - 1 = 7x - 3
7x - 6x = -1 + 3
x = 2

Substitute with x in equation I to get y as follows:
y = 3x - 1
y = 3(2) - 1
y = 6 - 1
y = 5

Hope this helps :)
