By solving algebraically......

1)

  • -2+17x= 10+15x
  • 17x-15x=10+2
  • 2x=12
  • x=6°

2)

  • 5+20x=22x-5
  • 22x-20x=5+5
  • 2x=18
  • x=5°

3)

  • 14x-6=120°
  • 14x-6+6=120+6
  • 14x=126
  • x=9°

4)

  • 10x+9+111=180°
  • 10x=180-120
  • 10x=60
  • x=6°

5)

  • 11x-6=6+9x
  • 11x-9x=6+6
  • 3x=12
  • x=4°

6)

  • 7+9x=70
  • 9x=70-7
  • 9x=63
  • x=7°

7)

  • 19x+1+65=180°
  • 19x=180-66
  • 14x=114
  • x=6°

8)

  • -4+9x=50°
  • 9x=54
  • x=6°

Hope this answers your question!
