Answer 1

@paki @sourwing Do you guys know this?

Answer 2

just solve the equation

or observe the use of associative property here use

Answer 3

get rid of parenthesis by distributing
compare both sides of the equation and cancel same term
-6-13 + 8 = -6 + m + 8
m = -13

yes use of associative property for addition
the order of associating does not matter
-6 -13 then + 8 = -19 + 8 = -11
-6 + m + 8 = m + 2 =-11 then m = -11 -2 =-13
