Question 813477
Two thirds times x plus four equals three fifths times x minus two?
{{{2/3}}}x + 4 = {{{3/5}}}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
{{{2/3}}}(-90) + 4 = {{{3/5}}}(-90) - 2
-60 + 4 = -54 - 2
