Well, for
solving system of equations, we can use either substitution where we plug one
equation into the other, or elimination where we combine the equations.
-
Using elimination,
you would to eliminate one variable from both equations, so you automatically would
get one equation with one variable!
Answer:
18.288 meters = 20 yards to be approximate
(or 18 meters if you round)
Hope this helps:)
In the Problem X=y2 the absolute variable is to be. A unit advance in y makes a change of 1/2 so the unit rate is 1/2.
