| A | B |
| x = 6y | One number is six times another. |
| x + (x + 1) + (x + 2) = 15 | The sum of three consecutive whole numbers is 15. |
| x = y - 3 | One number is three less than another number. |
| x = y + 5 | One number is five more than another number. |
| 2x + 7 = 15 | Seven more than twice a number is 15. |
| 2x + 8 = 24 | Double a number increased by 8 is 24. |
| 3x - 8 = 19 | Triple a number decreased by 8 is 19. |
| 40 + x = 4x | Forty increased by a number is four times the number. |
| 2x + 4 = 20 | Double a number increased by 4 is 20. |
