Substitute 2 for x in either equation and determine the value of y.

Juan, the two equations are linear equations (that is, they are two lines).  To "solve" means to find the (x,y) value that satisfies both equations (that is, the point where the lines intersect).  x=2, and be sure to solve for y in order to put the answer into (2,?) format (that is, an ordered pair).
