Answer:

Step-by-step explanation:

(5y - 2.3) + (-2y - 4.3) = 3y - n              Remove the brackets

5y - 2.3 - 2y - 4.3 = 3y - n                    Combine like terms

3y - 6.6 = 3y - n                                    Subtract 3y from both sidess

- 6.6 =  - n                                             Divide by - 1

6.6 = n
