Solving equations with one variable
Jonny is solving this equation for n: 8+3n=20. His first step is to subtract 8 from both sides of the equation. Why?

Jonny is subtracting 8 from both sides of the equation because he wants to isolate the variable "n" on one side of the equation. This is done by removing any constants (in this case, 8) from the side where the variable is located.
