**Reiny**, Tuesday, April 14, 2009 at 10:23pmI do it this way:

1. switch the x and y variables to get

x = 2y + 3

2. solve this new equation for y

2y = x - 3

y = (1/2)x - 3/2

some people solve the original for x fist, then switch the variables.

-makes no difference, same number of steps, same work, same result.
