Step-by-step explanation:

The unknown number is "X".

Let's write it in an equation form:

X - 19 = 10

Now solve for "X"

X - 19 = 10

We have to get the "X" by itself on one side of the equation. To do that, we have to move everything else to the other side. What you do on one side, you have to do on both sides. We are going to keep the "X" on the left side and move everything to the right side.

X - 19 = 10

+ 19 = + 19

_____________

X = 29
