Find the value of each variable so that the quadrilateral is a parallelogram. -2x + 6
X+ 12
y + 23
X =
y =

x = -2

y = -5

Step-by-step explanation:

Properties of a Parallelogram

Each diagonal is divided into two measures expressed with variables. Since diagonals bisect each other:

y + 23 = -4y - 2.  And

-2x + 6 = x + 12

Solve the first equation. Adding 4y:

5y + 23 = - 2

Subtracting 23:

5y = -25

Dividing by 5:

y = -5

Solve the second equation. Subtracting x and 6:

-3x = 6

Dividing by -3:

x = -2

Solution:

x = -2

y = -5

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
