3. to combine the equations and solve for one of the variables, you need to eliminate the other variable. how can you change one equation so that one variable is eliminated when the two equations are added? explain and write the new equation. 12x + 6y = 120 4x + y = 30 combine the two equations to eliminate one of the variables, and then solve for the other. solve for the other variable. prove that your solutions are correct by substituting the values back into the original equations and verifying the answers.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
