Twice a number added to -8is 24?

Answer 1

By rearranging the values according to the worded statement, we have 2n - 8 = 24. Thus, we solve.

Add 8:

2n = 32 (note that 24 = 3(8), and adding 8 makes 4(8), a basic 1 * 8 manipulation).

Divide by 2:

n = 16

Thus, n is 16.

Checking:

2(16) - 8 = 32 - 8 = 24.
