Simplify the given expression by doing each operation as per the order of operations. The order of operations is a systematic way of tackling an equation, that ensures that the result attained will be true when one solves the equation; remember, the order of operations states;
1. Parenthesis
2. Exponents
3. Multiplication/ Division
4. Addition/ Subtraction
Simplify the equation by combining terms as per the order of operations;
Graphing takes too long, substitution can sometimes complicate things quickly, therefore I would use elimination as my prime method of solving systems of equations.
