Tolong bantu ya.. 2x + y= 3(x-2) x - 3y= 4(2x+y-7) menggunakan metode apa saja..

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

x - 3y = 4 (2x+ y - 7)
x - 3y = 8x + 4y - 28
x - 8x = 3y + 4y - 28
-7x = 7y - 28

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

x-3y = 4(2x+y-7 )
x-3y = 8x +4y-28
x-8x -3y -4y = -28
-7x -7y = -28
