pada sistem persamaan 2x-3y=2 dan 3x=10+y tentukan nilai xpangkat3 -ypangkat3

Materi : SPLDV

2x - 3y = 2 ........ ×1
3x - y = 10 ......... ×3
◆◆◆◆◆◆◆◆◆◆◆◆◆◆
2x - 3y = 2
9x - 3y = 30
◆◆◆◆◆◆◆◆◆◆◆◆◆[-]
-7x = -28
x = 4

2x - 3y = 2
2(4) - 3y = 2
8 - 3y = 2
-3y = 2 - 8
-3y = -6
y = 2

Hp = { 4 , 2 }

Jadi :
》x^3 - y^3
》4^3 - 2^3
》64 - 8
》56

2x _ 3y = 2. x 3
3x _ y = 10. x 2

6x _ 9y = 6
6x _ 2y = 20
__________ _
_7y = _ 14
y = _ 14/_7
y = 2

2x _ 3y = 2
2x _ ( 3 x 2) = 2
2x = 2 + 6
2x = 10
x = 10/2
x = 5

dit : x^3 dan y^4
x^3 = 5x5x5 = 125
y^3 = 2x2x2 = 8
