A student, sitting at a wooden desk with pencil in hand, trying to solve a complex mathematical equation. In front of him, laid out on his notebook, is the equation 8 + 3n = 20. He is about to subtract 8 from both sides of the equation. He is in a well-lit study room, filled with piles of books and stationery. His expression is one of intense focus as he tries to solve the equation.

Jonny is solving this equation for n

8+ 3n = 20 His first step is to subtract 8 from both sides of the equation why

Subtracting 8 from both sides of the equation will isolate the variable n, allowing Jonny to solve for the value of n.

The reason why Jonny is subtracting 8 from both sides of the equation is to isolate the term containing the variable n on one side. By subtracting 8 from both sides, he is simplifying the equation and moving the constant term (8) to the other side of the equation. This will help in further solving the equation and finding the value of n.
