Answer:
X= 1.3
Step-by-step explanation:
If you need this to be a parallelogram, you need to found two pairs of parallel sides to be the same length.
The AB side has to be the same as the CD side.
So, to find x, you need to equal the two equations given, because both sides have to be the same.
[tex]2x+7=12x-6[/tex]
To find x first put all X terms to one side of the equal and no X terms to the other side.
[tex]7+6=12x-2x[/tex]
And you resolve
[tex]13=10x\\13/10=x\\1.3=x[/tex]
So, to have a parallelogram, the value of X is 1.3
