First, simplify the expression inside the parentheses:
(2×y + y + 9 + 8×y) = 10×y + 9

Now, substitute this back into the original equation:
(10×y + 9) ÷ 4 - 26 = 45

Now, distribute the division by 4:
10×y ÷ 4 + 9 ÷ 4 - 26 = 45

Reduce:
2.5×y + 2.25 - 26 = 45

Combine like terms:
2.5×y - 23.75 = 45

Add 23.75 to both sides:
2.5×y = 68.75

Divide by 2.5:
y = 27.5

Therefore, the solution to the equation is y = 27.5.
