Answer:

21) x = 0

23) x = 7

Step-by-step explanation:

In a parallelogram, the opposite sides are congruent. Using this fact, we can create equations for both problems.

21)

[tex]2x + 18 = 18[/tex]

Subtract 18.

[tex]2x = 0[/tex]

Divide by 2.

[tex]x = 0[/tex]

23)

[tex]2x - 3 = 11[/tex]

Add 3.

[tex]2x = 14[/tex]

Divide by 2.

[tex]x = 7[/tex]
