Answer:

1. n= 14

2. n=3

Step-by-step explanation:

For the first problem, let's break down the equation. The number being thought about can be represented by n. Then n is increased by 7, or simply put 7+ n. The sum is 21, so to find n you can use the equation 7 + n = 24 and solve for n, which is 14.

For problem two, the same strategy can be used. The number is n, multiplied by 9. So, 9 * n is equal to 27. Solve for n by isolating n, and the answer is 3.
