In order to find and simplify an algebraic equation we need a number.
Let's try number 74:
~Since 4 is in the units place, we can say x = 4 (x=unit places)
~The tens digit is 7 which is 3 more than 4. The tens digit can be written as an expression x + 3.
Now it's time to add the last parts of the equation as follows:
~ To get the value of the digit in the tens place, we have to multiply the tens digit with 10.
~In order to get the units place we need to add x at the end of the expression.
This is the final expression: 10 ( x + 3 ) + x
It can be simplified to: 10 x + 30 + x, which is further simplifies to 11 x + 30.
Lets test to see if it works:
11 ( 4 ) + 30 = 74
It works!
Just to be sure let's try another random number: 96
The x value in 96 is 6 because it's in the units place.
Now just plug it in the simplified expression: 11 x + 30
11 ( 6 ) + 30 = 96
This expression works for numbers whose tens digit is three more than the units digit.
Hopefully that helps!
