Question

What is (2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)

Answer 1

-20.2m -11.8

Explanation:

(2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)

Distribute the minus sign

(2y + 14.6m + 3.8) – 34.8m - 15.6 - 2y

I like to line them up vertically

2y + 14.6m + 3.8

– 2y -34.8m - 15.6

------------------------------

-20.2m -11.8
