Open in App

Solution

Step 1:
$(m - 3) - (- m + 12) = (m - 3) + (m - 12) {A d d t h e o p p o s i t e} = m + m + (- 3) + (- 12) {C o m m u t a t i v e p r o e r t y} = (m + m) + [(- 3) + (- 12)] {G r o u p s l i k e t e r m s} = 2 m + (- 15) {C o m b i n e l i k e t e r m s}$
Final Answer: The difference is $2 m - 15$
