Solve the following system by elimination.

[list=1] [*]Add the two equations if the coefficients of one of the variables are opposites of each other. [*]Solve the equation for the second variable. [*]Substitute the found value into either of the original equations to find the value of the other variable. [*]If graphed, the lines would cross at the coordinate found.
