penyelesaian dari 4/3x-y = 4 dan x + 1/2y=8 adalah..

Answer 1

4/3x - y = 4 ... ( 1 )
x + 1/2y = 8 ... ( 2 )

( 1 ) . 3
4x - 3y = 12 ... ( 3 )

( 2 ) . 2
2x + y = 16 ... ( 4 )

( 4 ) . 2
4x + 2y = 32 ... ( 5 )

( 3 ) - ( 5 )

- 5y = - 20
y = 4

4x + 2y = 32
4x + 2( 4 ) = 32
4x + 8 = 32
4x = 24
x = 6
