It is a linear equation in one unknown variable, n. Its solution is n = 1
6n + 5n is 11n.
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
I assume that you mean n = 3 6n + 4 = 6(3) + 4 = 18 + 4 = 22
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
In the expression 6n+3 the variable or the unknown is n
n is the variable.
It is a linear equation in one unknown variable, n. Its solution is n = 1
-5=6n+7 -5-7=6n+7-7 -12=6n -12/6=6n/6 -2=n
6n = 12 n = 2
The unknown variable in the expression: 6n+3 is n
15/6n + 6/6n = 21/6n = 7/2n
6n+5 = 11
If you mean -5(6n+6) = 30 then -30n -30 = 30 and so n = -2 when evaluated
6n + 17 = 5 subtract 17 from both sides 6n = -12 divide both sides by 6 n = -2 (negative 2)
6n + 5n is 11n.
6 is the coefficient, n is the variable, 3 is the constant
