Algebra
Step 1:Take the first card that the person picks to be x
Step 2:Next, take the second card that the person picks to be y
Step 3:Follow the steps as per given in the previous post.
X multiply by 2 which gives you 2x.
Add 5 to 2x, that gives you 2x+5
Multiply the number by 5, you will get 5(2x+5)
Add Y to the current equation, that will give you 5(2x+5)+y
The last step is to minus 25,resulting in 5(2x+5)+Y-25
Now expand the equation, you will get 10x+y
10x is the number in the tens place while y is the number in the ones place.
