Question 813477: Two thirds times x plus four equals three fifths times x minus two? My math book says the answer is -90 but I can't seem to get the steps leading to that answer. Please help! Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Two thirds times x plus four equals three fifths times x minus two? x + 4 = x - 2
Get rid of those annoying fractions, mult by 15, resulting in
10x + 60 = 9x - 30
10x - 9x = -3 - 60
x = -90; looks like the book is right

But you can confirm this yourself (-90) + 4 = (-90) - 2
-60 + 4 = -54 - 2
