set them equal to eac hother

7x-99=2x+1

-2x+99-2x+99

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

5 5

x=20

Answer 2

x = 20

Explanation:

The two angles are verticals angles and vertical angles are equal

7x -99 = 2x+1

Subtract 2x from each side

7x-99-2x =2x+1-2x

5x-99 =1

Add 99 to each side

5x-99+99 = 1+99

5x =100

Divide each side by 5

5x/5 =100/5

x = 20
