-2 x 5 = -10
-2 x 6n = -12n
(-10-12n)
6 x 8 = 48
6 x -2n = -12n
(48-12n)
(-10-12n)=(48-12n)
If you want to go further to solve for n then you would:
+10 on both sides 48+10 = 58
Now you have (-12n) = (58-12n)
Add 12n
(-12n + 12n) = 58
-12+12 = 0
N=58
(I’m pretty sure I did that correct. Sorry If I’m wrong)
