Here are the essential concepts you must grasp in order to answer the question correctly.
Solving Equations
Solving equations involves finding the value of a variable that makes the equation true. In this case, we need to isolate 'y' in the equation x = 5/y + 4. This process typically includes rearranging the equation, using algebraic operations such as addition, subtraction, multiplication, and division to isolate the variable of interest.

Reciprocal Relationships
The concept of reciprocals is crucial when dealing with fractions and variables. The reciprocal of a number is 1 divided by that number. In the equation x = 5/y + 4, understanding how to manipulate the term 5/y is essential, as it can be rewritten in terms of y by multiplying both sides by y to eliminate the fraction.

Linear Equations
Linear equations are equations of the first degree, meaning they involve variables raised only to the first power. The equation x = 5/y + 4 can be transformed into a linear form by eliminating the fraction and rearranging terms. Recognizing the structure of linear equations helps in applying methods for solving them, such as substitution or elimination.
