$8-2y-3\left( y+3 \right)=-11$
Distribute $-3$ through the parentheses$8-2y-3y-9=-11$
Calculate the difference$-1-2y-3y=-11$
Collect like terms$-1-5y=-11$
Move the constant to the left-hand side and change its sign$-1-5y+11=0$
Calculate the sum$10-5y=0$
Divide both sides of the equation by $5$$2-y=0$
Use the commutative property to reorder the terms$-y+2=0$
Change the signs on both sides of the equation$y-2=0$
