2x = 60°
x = 60° : 2
x = 30°
No 2b.
4x + 40° = 120°
4x = 120° - 40°
4x = 80°
x = 80° : 4
x = 20°
No 3a.
3x + 60° = 120°
3x = 120° - 60°
3x = 60°
x = 60° : 3
x = 20°
No 3b.
3x + 15° = 75°
3x = 75° - 15°
3x = 60°
x = 60° : 3
x = 20°
No 4a.
5x° = 40°
x° = 40° : 5
x° = 8°
No 4b.
7x + 25° = 130°
7x = 130° - 25°
7x = 105°
x = 105° : 7
