Question

.What is the value of y in parallelogram LMNO? There is a picture attahed i need help fast @ChmE

Answer 1

The diagonals of a parallelogram bisect each other.
That means y = 3x and y + 12 = 6x
You need to solve that system of equations.

Answer 2

@mathstudent55 okay so do i plug in 3x iinto the equation

Answer 3

yes, you can substitute 3x into the 2nd equation to solve for x

Answer 4

Since y = 3x, plug that in for y of the other equation:
3x + 12 = 6x

Answer 5

okay and do i combin like terms 3x and 6x

Answer 6

That will give you x, then plug the value of x into y = 3x, and you'll get y.

Answer 7

i have 4x

Answer 8

so y is 12 right

Answer 9

@mathstudent55 y is 12

Answer 10

3x + 12 = 6x
12 = 3x
x = 4
y = 3x
y = 3(4)
y = 12
