Question

Help me as quick as possible
11x+4y=12
9x-4y=8
Solve it with elimination method

Answer 1

x = 1, y = 1/4

Explanation:

`11x + 4 y = 12 \ \ \ ---( 1)\\9x -4y = 8 \ \ \ - - - (2)\\\\(1) + ( 2 ) => 20x + 0 = 20\\\\`

`=> x = 1`

Substitute x = 1 in ( 1 ) :

`11 + 4y = 12\\4y = 12 - 11\\\\y =(1)/(4)`
