Answer:

number is 34

Explanation:

let the number be n then the difference of n and 19 is n - 19

multiplying n - 19 by - 7 gives - 105

the equation is then

- 7(n - 19) = - 105 ( divide both sides by - 7 )


(-7)/(-7) (n - 19) =
(-105)/(-7) ( simplify both sides )

n - 19 = 15 ( add 19 to both sides )

n - 19 + 19 = 15 + 19 , that is

n = 34

the number is 34
