Answer 1

Answer:

x=4

Step-by-step explanation:

In a parallelogram opposite sides are congruent. That means BC and AD are congruent if ABCD must be a parallelogram.

$6+3x=x+14\\6+2x=14\\2x=8\\x=4$

To double check you can substitute x into the equations again and check if they are equal.

$6+3(4)=(4)+14\\6+12=18\\18=18$
