2/15 + y - 7/30 = 1/10

First, we need to combine the fractions on the left side:

2/15 - 7/30 + y = 1/10

To combine the fractions, we need to find a common denominator. The common denominator for 15 and 30 is 30:

(4/30 - 7/30) + y = 1/10
(-3/30) + y = 1/10
-1/10 + y = 1/10

Now, isolate y by adding 1/10 to both sides:

y = 1/10 + 1/10
y = 2/10
y = 1/5

Therefore, the solution to the equation is y = 1/5.
