1) Add corresponding sides of the equations: , or . Substituting this into the top equation, we get . Thus there are 4 solutions: (, -2), (, 2), (, -2), (, 2). (They represent the intersection points of a circle centered at (0,0) with radius 3 and a hyperbola with transverse axis corresponding to the x-axis.)

2)Multiply the top eq'n by 2, and then add corresponding sides: , or . Substituting into the lower eq'n, we get , or , or y = -1/2. Thus there are 2 solutions: (-3, -1/2) and (3, -1/2).

3) Multiply the top eq'n by 2, and then add corresponding sides: 1/y = 3, or y = 1/3. Substituting into the top eq'n, we get: , or , or x = 1/5.
