Enter the value of n so the expression (-y + 5.3) + (7.2y-9) is equivalent to 6.2y + n.
Please explain what and how you did it. I've seen other answers for the same question, but they do not make sense.

If you would like to find the value of n, you can calculate this using the following steps:

(- y + 5.3) + (7.2 * y - 9) = - y + 5.3 + 7.2 * y - 9 = - y + 7.2 * y + 5.3 - 9 = 6.2 * y - 3.7

6.2 * y - 3.7 = 6.2 * y + n
n = - 3.7

The correct result would be - 3.7.
