Concept used:
Distributive law:
In mathematics the law relating the operations of multiplication and addition, stated symbolically:
Here monomial factor
Probably the most common thing it will be doing with polynomials is combining like terms.
This is the process of adding together whatever terms it can, but not overdoing it by trying to add together terms that can’t actually be combined and term can combined only if there has the exact same variable portion and exact same variable portion and by exact same.
Calculation:
To find the number of dimes used first define a variable as:
Let
The equation can be written as:
By distributing and combining the like terms:
Hence, it is not possible to have
