The equation "9n equals 126" can be written as 9n = 126.
If you mean n times 7 equals 56... Then the value of n is 8 !
Write it as an equation: n/7 - 8 = 10 Add 8 to bot sides: n/7 = 18 Multiply both sides by 7: n = 126
23 *n=568*n=56n=56/8n=7
3 squared is 9 and so 9n = 63 which means n = 7

3 (n + 7) = 16
k = f(n) = 7n
23 *n=568*n=56n=56/8n=7
You have one linear equation in two unknown variables: A and n. There can be no solution.
n = 8
7 + n = 14 n = 7
3 squared is 9 and so 9n = 63 which means n = 7
