Question

Plz I need this helpppppppp

Answer 1

Explanation:

n=9 so you have to substitute the n with 9 and then you get the number 99 and then you have to add 99+1 and that equals 100

Answer 2

n = 11

Explanation:

100 = 9n + 1

Subtract 1 from both sides.

(100) - 1 = (9n + 1) - 1

99 = 9n

Divide both sides by 9.

(99)/9 = (9n)/9

11 = n

Your answer is 11.
