In Exercises 47–48, solve each system by the method of your choice. (x - y)/3 = (x + y)/2 - 1/2 (x + 2)/2 - 4 = (y + 4)/3

In Exercises 47–52, solve each system by the method of your choice. $\(\begin{cases}\)2x^2 + xy = 6 \(\x\)^2 + 2xy = 0\(\end{cases}\)$

In Exercises 49–50, solve each system for x and y, expressing either value in terms of a or b, if necessary. Assume that a ≠ 0, b ≠ 0 5ax + 4y = 17 ax + 7y = 22

In Exercises 47–48, solve each system by the method of your choice. (x + 2)/2 - (y + 4)/3 = 3 (x + y)/5 = (x - y)/2 - 5/2

In Exercises 47–52, solve each system by the method of your choice. $\(\begin{cases}\)-4x + y = 12 \(\y\) = x^3 + 3x^2\(\end{cases}\)$

Graph the solution set of each system of inequalities or indicate that the system has no solution.

$\(\begin{cases}\)x^2 + y^2 > 1 \(\x\)^2 + y^2 < 16\(\end{cases}\)$

In Exercises 46–55, graph the solution set of each system of inequalities or indicate that the system has no solution.
