1. What are Linear Equations?
A linear equation is an equation that contains variables that have an exponent that is no higher than one.
Example: y = 3; x + 3 = 5; 2x + 5 = 9
2. How to solve Linear Equations?
- Equations have an equals sign in them to show that the values on the left-hand side are equal to the values on the right-hand side.
- One can solve Linear equations by finding the value of the variable.
- First remove parts of the equation until the variable is left on its own on one side of the equal to sign.
- To remove part of an equation, perform the opposite operation to both sides of the equation.
