10n + 3 = 7n + 53n = 2n = 2/3
10n = 1,000,000 n= 1,000,000 divide by 10 n= 100,000

7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
so you set it up. 10n+5 divide each side by 5 n=2
5n - 4 = 10n + 6-5n = 10n = -2
-19 + 9 = -10n = -19n+9=-10-9 -9n=-19
10n + 3 = 7n + 53n = 2n = 2/3
It has to be interval notation
10n+2
10n + 3 = 93 Therefore, 10n = 90 n = 90/10 n = 9
n = 26
10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
10n. Just count up how many ns there are.
It is an equation and the value of n is 9
5n+6=-45n=-10n=-2
10n = 80.n = 8.
