3/10x+ 1/6y+3/10x +3/6y

To simplify the expression, combine like terms:

3/10x + 1/6y + 3/10x + 3/6y

Combining the x terms, we have:

(3/10x + 3/10x) + 1/6y + 3/6y
(6/10x) + 1/6y + 3/6y

Simplifying the y terms, we have:

(6/10x) + 1/6y + (3/6) * y
(6/10x) + 1/6y + 1/2y

Now, let's focus on the y terms and find a common denominator:

(6/10x) + (1/6 + 3/6)y
(6/10x) + (4/6)y

The common denominator is 6.

Now, let's simplify the fractions:

(3/5x) + (2/3)y

Therefore, the simplified expression is 3/5x + 2/3y.
