How do u solve it i know its a parallelogram

x = 70

Step-by-step explanation:

In this picture, 139 and (7x-1) are on opposite sides of each other, meaning they are equal to each other. To solve for x, just make them equal to each other first.

1. 7x-1 = 139

2. Add 1 to both sides to isolate 7x.

7x = 140

3. Divide both sides by 7 to isolate x.

x = 70

4. Your answer is 70.

Hope this helped!
