Answer:

Three Methods: substitution, elimination, and graphing.

Step-by-step explanation:

Graphing: To find the solution of a system of equations on a graph, you find the point of intersection of the two lines.

Elimination:

  1. Multiply each equation by a certain number to get the LCM for one of the variables.
  2. Add/subtract the two equations to get rid of that variable.
  3. Substitute that variable into one equation and solve for the remaining variable.

Substitution:

  1. Solve an equation for one of its variables. (either x or y)
  2. Substitute this equation into the other equation and simplify/solve.
  3. Resubstitute the number into the original equation (#1) to find the other variable.
