First, simplify the expression inside the parentheses:

3y + 4 + y + 3y = 7y + 4

Now substitute this back into the original equation:

52 - (7y + 4)/38 = 50

Next, multiply both sides of the equation by 38 to get rid of the denominator:

38(52) - 7y - 4 = 50(38)
1936 - 7y - 4 = 1900
1932 - 7y = 1900

Now, solve for y:

7y = -32
y = 32/7
y = 4.57 (rounded to two decimal places)

So, y is approximately 4.57.
