-3(y-5)=24 First follow the distributive property and do the parentheses. -3 times y gives you:-3y -3 times -5 gives you 15 since a negative times a negative is a positve. So now you have -3y +15 = 24 subtract 15 from both sides and you will get: -3y+15-15=24-15 which then gives you: -3y= 9 to get y by itself divide both sides by -3. this gives you: y= -3
