27) If the product of 6 and an integer, n, is increased by 13, the result is -14. What is the value of n? 

1. -4.5
2. 4.5
3. 162
4. 148

Let n = the integer.

The product of two values is the result of multiplying them. "Increased by" means to use addition. Therefore, you get this equation:

6n + 13 = -14

Isolate the variable.

6n = -27

Divide both sides by 6.

n = -4.5
