Add and simplify the problem. What is y?

(10y+30x=20)+(6y+30x=60)

To solve for y, we first need to combine the two equations:

10y + 30x = 20
6y + 30x = 60

Adding these two equations together, we get:

16y + 60x = 80

Now we can simplify this equation by dividing by 16:

y + 3.75x = 5

Therefore, the value of y is y = 5 - 3.75x.
