selesaian dari sistem persamaan 3 x tambah 2 Y kurang 4 = 0 dan X kurang 3 Y kurang 5 = 0 adalah

3x + 2y - 4 = 0
x - 3y - 5 = 0

3x + 2y - 4 = 0
3x + 2y = 4

x - 3y - 5 = 0
x - 3y = 5

3x + 2y = 4|× 3
x - 3y = 5|× 2

9x + 6y = 12
2x - 6y = 10
_________+
11x = 22
x = 2

x - 3y = 5
2 - 3y = 5
- 3y = 5 - 2
- 3y = 3
y = - 1

Maaf Kalau Salah
