The most important step is to get rid of all the pesky fractions.
Multiply by 30. So:
2x + 5 = 0
so
x = -5/2.

you could clear the fractions by multiplying each term by the LCD= 30
30(x/15) +30(1/6) = 30(0)
2x + 5 = 0
2x = -5
x = -5/2
Or, keeping the fractions
x/15 = -1/6 then move the 15 over by multiplying
x = 15(-1/6)
x = -5/2

First subtract 1/6 from both sides so x/15=-1/6
Then do cross-products and x = -2.5

x/15 + 1/6 = 0 (subtract 1/6 both sides)
x/15 = -1/6 (multiply with 15 both sides)
the answer well be
x = -15/16

x/15 = -1/6 times by 15
x= -15/6

ok, subtract 1/6 from each side to get:
x/15 = -1/6.
Then multiply both sides by 15 to get:
x= -15/6

Subtract 1/6 from both sides then multiply both sides by 15.

x/15 + 1/6 = 0
90(x/15 + 1/6 = 0)
6x + 15 = 0
6x = -15
x = -15/6

x/15 + 1/6 = 0
x/15 = -1/6
x = -15/6 = -5/2

Try to isolate the variable.
Subtract 1/6. x/15 = -1/6
Divide by 15. x= -15/6
Simplify. x= -5/2
OR -2.5
