Adem writes 18y to simplify an expression with three like terms. What could the expression be? Simplify the expression you wrote for part a to check your answer

1. 7y + 6y + 5y

2. 7y + 6y + 5y = y (7 + 6 + 5) = 18y

Step-by-step explanation:

1. 18 can be separated into 7,6,5

that means 7y + 6y + 5y will work

2. 7y + 6y + 5y

factorizing the like-tern out

= y (7 + 6 + 5)

adding the numbers in parenthesis

= 18y
