Question

Use elimination to solve.

5x-9y+53=0
9x-5y-53=0

Answer 1

\[(\frac{53}{4},\frac{53}{4})\]

Answer 2

steps please.

Answer 3

5x-9y+53=0
x= 1/5 (-53+9 y)

------
9x-5y-53=0
9(1/5 (-53+9 y))-5y-53=0
y= 53/4

----
x= 1/5 (-53+9 y)
x= 1/5 (-53+9 (53/4))
x= 53/4

(53/4,53/4)


I dont think this is the method you asked for, but really this is the only method you need until you do complex variables... So, its all I remember :X
