What number gives a result of -4 when 9 is subtracted from the quotient of the number and 5?
Vera_Pavlovna [14]
Answer:

25

Step by step:

1. prepare the equation

-4 = x/5 - 9

2. add 9 to both sides

-4 = x/5 - 9
+9 +9
5 = x/5

3. multiply both sides by 5

5 = x/5
(5) (5)
25 = x

4. x=25

Hope this helps
