Question 479282
Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
5x – 4y = 10.5
20x – 16y = 42

----
Multiply thru the 1st equation by 4:
20x - 16y = 42
20x - 16y = 42
----
The two equations are the same.
Infinite # of solutions: (x,(5/4)x-(10.5/4)) where x is any Real Number.
