For which value or values are the expressions 15k+9 and 3 (2k+3) + 9k

Remember you can do anthing to an equaiton as long as you do it to both sides

I think you are missing a relation symbol at the end

it could be an equals though (just my guess)

For which value or values are the expressions 15k+9 and 3 (2k+3) + 9k equal

15k+9=3 (2k+3) + 9k

use distributive prpoerty which says

a (b+c) = ab+ac so

3 (2k+3) = 6k+9

now we have

15k+9=6k+9+9k

add like terms

15k+9=15k+9

subtract 9

15k=15k

divide 15

k=k

since this is a true statement, any number will work for k

k=all real numbers
