6. Consider the system of equations ax 3y = 7 2x + 4y = 4 (a) (2 points) Explain why we don't need to use Newton's method for systems to solve for (x, y). If you don't know how to answer this right away, consider part (b) first. (b) (2 points) If we did apply Newton's method for systems to solve it, what will the Jacobian be? Will we get the right solution when we use Newton's method for systems
