Han's age decreased by

19 is 70
Translate this into an equation

H - 19 = 70

To translate the given statement into an equation, let's define some variables:

Let H be Han's current age.
Let D be the decrease in Han's age.

According to the statement, "Han's age decreased by 19 is 70," we can write an equation using the variables defined above:

H - D = 70

In this case, we need to find the value of D (decrease in Han's age), given that the final age is 70.
