You can solve a system of equations 3 ways.
1. Elimination
This method is eliminates one of the variables in the system of equations to get 1 equation with only one 1 variable.
2. Graph
You graph both of the equations and find where they intersect if at all.
3. Substitution
If you know the value of one of variables, you can substitute it back into the equation.
