Question

If 39 is added to a number, it will be 4 times as large as it was originally. What's the number?

Answer 1

Answer:

117

Step-by-step explanation:

Let the added number be (x)

39 + x = 39 × 4

x = 156 - 39

x = 17

Answer 2

13

Step-by-step explanation:

let the number=x

x+39=4x

39=3x

x=39/3=13

Check: 13+39=52

             4*13=52
