Question

Julio says," if you subtract 19 from my number and multiply the difference by -3, the result is -15." what is Julio's number?

Answer 1

answer is 5

Explanation:

`- 3(x - 19) = - 15`

cancel out both sides by -3, therefore -15 will become positive

`( - 3(x - 19))/( - 3) = ( - 15)/( - 3)`

then add 19 to both sides

`x - 19 +19= 5 + 19`

then X will add up to 24

Answer 2

24

Explanation:

24 - 19 = 5

5 * -3 = -15
