The sum of 5 times a number and 9 equals 3.

n = - 1.2

Step-by-step explanation:

Step 1: Convert words into an expression

The sum of 5 times a number and 9 equals 3.

(5 * n) + 9 = 3

5n + 9 = 3

Step 2: Subtract 9 from both sides

5n + 9 - 9 = 3 - 9

5n = - 6

Step 3: Divide both sides by 5

5n / 5 = - 6 / 5

n = - 1.2

Answer: n = - 1.2
