SOLVING LINEAR EQUATIONS
Recall the following:
- A linear equation is a polynomial of degree 1.
- In order to solve for the unknown variable, you must isolate
- In the order of operations, multiplication and division are completed
before addition and subtraction.
LINEAR EQUATION - Solve for x in the following equation.
The answer is x=-1
Check the solution by substituting -1 in the original
equation for x. If the left side of the equation equals the right side
of the equation after the substitution, you have found the correct
Since the left side of the original equation equals the right
side of the original equation when the value 1 is substituted for x,
the solution x = -1 is verified.
