-x/3 - 5 = 2x
multiply both sides of the equation by 3
-x - 15 = 6x
combine x terms
-15 = 7x
divide both sides by 7
-15/7 = x

-x/3 - 5 = 2x
-x/3 = 2x + 5
-x = 6x + 15
-7x = 15
x = -15/7
x = -2.142857'

-x/3 - 5 = 2x
add 5 to both sides gives:
-x/3 = 2x + 5
multiply both sides by 3 gives:
-x = 6x + 15
Surely you can do it from there!

(-X / 3) - 5 = 2X
(-X / 3) = 2X + 5
-X = 6X + 15
-7X = 15
X = -15/7 (or -2 1/7)
