Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.
17 + -2y = 6 + 2y + -2y

Combine like terms: 2y + -2y = 0
17 + -2y = 6 + 0
17 + -2y = 6

Add '-17' to each side of the equation.
17 + -17 + -2y = 6 + -17

Combine like terms: 17 + -17 = 0
0 + -2y = 6 + -17
-2y = 6 + -17

Combine like terms: 6 + -17 = -11
-2y = -11

Divide each side by '-2'.
y = 5.5

Simplifying
y = 5.5
