When you solve an equation, you manipulate the given equation to determine the values of the variables that satisfy the equation. The primary goal is to isolate the variable on one side of the equation.
Having the variables "cancel out" means that you can simplify the equation by performing operations that eliminate the variables from the equation. This process is usually done by applying inverse operations to both sides of the equation.
In the example you mentioned, "3=3," it indicates that both sides of the equation are equal. This equation indicates that any value for the variables would satisfy it. Therefore, there are infinitely many solutions, meaning any value for the variables that you substitute into the equation would make it true.
What does it mean to solve an equation, have the variables cancel out, and have the answer be 3=3, for example?
