This question as written can be taken two ways: 9m + 6n - 3m + 7n = 6m + 13n, or (9m + 6n) - (3m + 7n) = 9m + 6n - 3m - 7n = 6m - n
It is a linear equation in one unknown variable, n. Its solution is n = 1
7n3 + 6n = n*(7n2 + 6)
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
10n + 3 = 7n + 53n = 2n = 2/3

6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
It is a linear equation in one unknown variable, n. Its solution is n = 1
7n3 + 6n = n*(7n2 + 6)
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
6n + 7n = 13n
6n + 7n (= 13n)
(10, 2)
22n + 2.
6m + 5n - 4m + 7n = 2m + 12n
9 - 5n
10n + 3 = 7n + 53n = 2n = 2/3
