x = 10
x = 27
Step-by-step explanation:
53 and 5x + 3 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
53 = 5x + 3
subtract 3 from both sides of the equation
53 - 3 = 5x + 3 - 3
50 = 5x
divide both sides of the equation by 5
50/5 = 5x/5
10 = x
82 and 3x + 1 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
82 = 3x + 1
subtract 1 from both sides of the equation
82 - 1 = 3x
81 = 3x
divide both sides of the equation by 3
81/3 = 3x/3
27 = x
