Ryan, jessica, and mark each solved this system of equations. all of their answers are different. find and explain the mistakes.
y = 3x + 2 6x 2y = 10
ryans i solved by adding the equations. the solution is . y = 3x + 2 ? 3x + y = 2 6x 2y = 10 ? 3x y = 5 6x = 7 x = 6x 2y = 10 ? 6 2y = 10 7 2y = 10 2y = 3 y = - jesses i used matrices. the solution is . marks i graphed the equations. the lines are parallel and do not intersect, so there is no solution.
