your first step will be distributing the -5 to the binomial inside the parenthesis
14y - 5(3 - 2y)
14y - 15 + 10y
you carry the sign of the number when distributing so the sign of 2y changes to a positive
from here, you add like terms--so all of the terms with the y variable
14y - 15 + 10y
24y - 15
and after adding like terms there's nothing more you can do to simplify this expression, so 24y - 15 is your answer!!
