The required difference when (-5x + 4y) is subtracted from (7x + 9y) in simplest terms is 12x + 5y.
Given that,
To find an expression that represents the difference when (-5x + 4y) is subtracted from (7x + 9y) in simplest terms.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements.
What is simplification?
The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
= 7x + 9y - (-5x + 4y)
= 7x +9y + 5x - 4y
= 7x + 5x + 9y -4y
= 12x + 5y
Thus, the required difference when (-5x + 4y) is subtracted from (7x + 9y) in simplest terms is 12x + 5y.
