Answer:

X=3

Step-by-step explanation:

To the question

Let the number be x

And being 5 times of the number is 5x

And been increased by 4

(5x+4)=19

5x+4=19

Substrate 4 from both sides

5x=15

Divide both sides by 5

X=3

Answer:

The number is 3

Step-by-step explanation:

First we want to make an equation, 5 times n (a number) plus 4 = 19 (by using 19 the least possible awnser we know that it will be the least possible number that satisfied the requirements, if it didn't work we could have gone up one number until we found something that worked)

5n +4 =19 subtract 4 from both sides so that the 5n is alone

5n = 15 now divide by 5 so that the n is all alone

n=3
