Pls help im timed!! 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 3% – 2y = 4 and
9x-by = 12 with his graphing calculator, but he could only see one line. Why is this?
O because the system of equations actually has only one solution
because the system of equations actually has no solution
O because the graphs of the two equations overlap each other
because the graph of one of the equations does not exist
