Solving a System of Equations Graphically When ________________, you find the intersections of two graphed lines
Solving a System of Equations by Using Substitution Substituting one equation into the other equation in a system of equations. Once the value for either x or y is found, find the other value by substituting your first answer into any original equation.
Solving a System of Equations by Using Elimination Eliminating either x or y by subtracting or adding all values together so x or y is equal to zero. To find the other value, substitute your original answer into any of the equations.
Solutions to a System Remains a Solution if ___________________... (1) Properties of equality are used to rewrite either of the equations, and (2.) the equations are added or subtracted or any rewrite is added or subtracted.
