Question

2x+3y=5, 6x-3y=5 solve by elmination method

Answer 1

2x + 3y = 5------------( 1 )
6x - 3y = 5--------------( 2 )


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

2x + 3y = 5
6x - 3y = 5
–––––––––
8x = 10

X = 5/4 [ put in -----( 1 ) ]

2(5/4) + 3y = 5

5/2 + 3y = 5

(5 + 6y)/3 = 5

5 + 6y = 15

6y = 15 - 5

6y = 10

Y = 5/3 , x = 5/4
