Equations with variables on both sides: positive numbers

Year 8 maths · Fieldbook Learning

Name ______________________ Date __________

Collect the x terms on one side and the plain numbers on the other, then divide.

  1. Solve for x: 3x + 10 = x + 12
  2. Solve for x: 2x + 9 = 3x + 3
  3. Solve for x: 3x − 1 = x + 15
  4. Solve for x: 2x − 6 = 3x − 9
  5. Solve for x: 2x − 15 = 4x − 33
  6. Solve for x: 2x + 14 = 8x − 28
  7. Solve for x: 7x + 12 = x + 66
  8. Solve for x: 8x − 16 = 2x + 2
  9. Solve for x: 11x − 19 = 4x + 58
  10. Solve for x: 3x − 19 = 9x − 91
  11. Solve for x: 3x + 23 = 7x + 19
  12. Solve for x: 9x + 17 = 8x + 29
  13. Solve for x: 4x − 1 = 13x − 109
  14. Solve for x: 13x − 9 = 2x + 134
  15. Solve for x: 2x + 14 = 3x + 1
  16. Solve for x: 7x − 27 = 14x − 104
  17. Solve for x: 10x − 31 = 4x − 13
  18. Solve for x: 9x + 12 = 19x − 78
  19. Solve for x: 10x − 30 = 4x + 36
  20. Solve for x: 4x + 34 = 18x + 20
