When a number is divided by -3, the result is 12 more than the number. What is the number?
otez555 [7]

Answer:

x = -9

Step-by-step explanation:

let the number = x

                                So  x ÷ -3 = x + 12

Mulitply both sides by -3:    x = -3x -36

Add 3x to both sides:        4x = -36

Divide both sides by 4:        x = -9
