Question

What are 3 methods for solving a linear system of equations?

Accepted Answer

**substitution:** solving one equation for *x* or *y* and substituting its value into the other equation to solve for one variable, then plugging this value into either equation to solve for the other variable.    
**elimination:** manipulating the equations so that adding the first equation to the second will eliminate one of the variables so that the second variable can be solved for    
**graphing:** graphing both equations and finding their point of intersection
