If one-half of *y* has a weight of 5, then one *y* has a weight of 5 × 2 = 10. In other words, to get the solution, we multiply both sides of the equation by 2, or the multiplicative inverse of . In the meantime, we would like to know who's been going around sawing variables in half. Whoever it is had better have a license to do that sort of thing. | |
