Question

Can someone help me pls!!

Answer 1

Answer:

$a=1$

Step-by-step explanation:

A parallelogram is a quadrilateral with two pairs of parallel sides. Opposite sides of a parallelogram are equal.

Therefore, set any two opposite sides equal to each other to solve for $a$:

$a+3=2a+2,\\\\3=a+2,\\a=\boxed{1}$

Answer 2

Answer:

a+3 = 2a+2

a+6 = 6a+1

-------------

a = -1

5a = -5

a = -1

a = -1
