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?
because the system of equations actually has only one solution
Obecause the system of equations actually has no solution
O because the graphs of the two equations overlap each other
O because the graph of one of the equations does not exist
