What is a linear equation?
A linear equation is an equation where the highest power of the variable is 1, such as 2x + 3 = 7.
When does a linear equation have no solution?
When simplifying leads to a contradiction like 0 = 5, meaning no value of x satisfies the equation.
When does it have infinite solutions?
When both sides simplify to the same expression (e.g., 0 = 0), meaning every value of x is a solution.
