URGENT IM DOING A TIMED QUIZ To solve the system of linear equations 3x-2y = 4 and 9x-by = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by -3 and then add the two equations together to eliminate the x- terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3x – 2y = 4 and 9x-by = 12 with his graphing calculator, but he could only see one line. Why is this?
