I haven't done any algebra in years and I need to solve the following equation for x. Can anyone help me, or at least tell me how to go about it.
237.7y + xy - 7.5x = 0
Here's one similar to your equation that I prepared earlier, model the steps from here and your's should be a piece of cake (hopefully chocolate cake)
leaving the x terms on the LHS
Factor out the x
divide the other factor over to the RHS and bingo!
