Answer:
46
Step-by-step explanation:
Let represent a number with in the ten's position and is the one's position.
This means actually has value of .
We are given the sum of those digits of is 10; this means .
It says if 18 is added to the number , then the result is .
So has value and
has value .
We are given then:
Subtract on both sides:
Simplify:
Subtract on both sides:
Divide both sides by 9:
Rearrange by commutative property:
So the system of equations we want to solve is:
-------------------------Add equations together (this will eliminate the variable and allow you to go ahead and solve for :
Divide both sides by 2:
Simplify:
If and , then . since 4+6=10.
So the original number is (46).
18 more than 46 is 18+46=(64) which is what we wanted.
We also have the sum of 4 and 6 is 10 as well.
