Types of Linear Equations:
1. Conditional Equation is an equation that is only true for a specific value of the variable, which is the solution.
If the conditional equation is not linear, it is possible to have more than one solution.
2. Identity is an equation that is always true and has infinite solutions.
3. Contradiction is an equation that is always false and has no solution. We can also say that the equation is inconsistent.
Difference between an expression and an equation :
An Expression is a mathematical phrase that combines numbers and/or variables using mathematical operations.
An Expression can be evaluated but not solved, and therefore expressions do not contain equal signs.
An Equation is a mathematical sentence that combines numbers and/or variables, that shows the equality of two expressions.
