graph both linear equations, and where the lines intersect is the solution of this system.

Well, you can solve for y for both and graph the lines and get y=3x-1 and y=3x-2, but you will find that these lines are parallel, so there is no solution to this system. Normally, the solution(s) occur when the lines intersect, but since there is no intersection, there is no solution.

Well, those lines have the same slope (they don't intersect). The problem could be written incorrectly. Otherwise, "good luck."

u have to solve first the values of x and y. you can then graph each equation.
