Question

Solve each of the following system of equations by elimination method.

Answer 1

HELLO DEAR,



13x + 11y = 70-------------( 1 )
11x + 13y = 74-------------( 2 )


subtracting from----( 1 )&----( 2 )

13x + 11y = 70
11x + 13y = 74
---------------------
2x - 2y = -4

x - y = -2----------( 3 )


adding -----( 1 ) & -----( 2 )

11x + 13y = 74
13x + 11y = 70
---------------------
24x + 24y = 144

x + y = 6----------( 4 )


from-------( 3 ) & -----( 4 )

x - y = -2
x + y = 6
-------------
2x = 4

x = 2 [ put in ----( 3 ) ]


x - y = -2

2 - y = -2

y = 4 , x = 2



I HOPE ITS HELP YOU DEAR,
THANKS
