Answer
14y - 15
Work Step by Step
4(5y - 3) - (6y + 3)
Use the distributive property to remove the parentheses
=4.5y - 4.3 - (6y+3)
Drop parentheses and change the sign of each term in parentheses: -(6y+3) = -6y -3
= 4.5y -4.3 - 6y-3
Multiply
= 20y - 12 -6y -3
Group like terms
= (20y - 6y) - (12+3)
combine like terms (20y - 6y) = (20-6)y = 14y, (12+3) =15
14y - 15
