5. Consider the system of equation: x+4y=13 3x+2y=19 (a) Multiply both sides of the second equation by -2. What equation results? (b) Add the equation from (a) to the first equation. What happens? What can you now solve for? (c) Now that you know the value of x, how can you find the value of y? Find it. (d) What could you have multiplied both sides of the first equation by to eliminate the x instead of the y
