N - 8 = 43
Your goal is to isolate the variable (in this case the variable is N).
You need to get rid of the -8. The opposite of -8 is +8. You need to add 8 to each side.
N - 8 + 8 = 43 + 8
The -8 and +8 cancel each other out.
N = 51

n-8=43
n = 43 +8 [You can move a term from one side to other if you change the sign]
n= 51

N - 8 = 43
N = 51 {add 8 to both sides}

n-8=43
+8=+8
n=51
the opposite of adding is subtracting. The opposite of subtracting is adding. the opposite of multiplying is dividing and vice versa.
