6m + 5n - 4m + 7n = 2m + 12n
22n + 2.
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7

6m + 5n - 4m + 7n = 2m + 12n
22n + 2.
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7
3n + 3(6 + 7n) = 3n + 18 + 21n = 24n + 18

I'm assuming you are solving for n.2n + 6 = 7n - 9 {add nine to each side}2n + 15 = 7n { subtract 2n from each side}15 = 5n {divide each side by 5}3 = n
If the forces acting on an object are equal there is no motion (5N->O<-5N). If the forces are unequal there is movement (7N-->O<-5N).
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
The net force is 2N north. This is because when you subtract the 5N force south from the 7N force north, you get a resultant force of 2N north.
A variable comes after the number 2n+5n=7n
7n-6 = 1
