-5x+3y=-24
persamaan kedua dikali -1
jadi... x-2y=2 |× 3 | 3x - 6y = 6
5x-3y=24 |× 2 | 10x - 6y = 48
__________ -
- 7x = - 42
x = 6
x - 2y = 2
(6) - 2y = 2
- 2y = - 4
y = 2
8. x - y = 3 |× 2|2x - 2y = 6
2x + 3y = 16 |× 1|2x + 3y = 16
_________ -
- 5y = - 10
y = 2
x - y = 3 (y dimasukin trserah ke pers 1 atau 2)
x - 2 = 3
x = 5
9. 5x + y = 10 |×2|10x + 2y = 20
4x - 2y = -6|×1|4x - 2y = -6
__________ +
14x = 14
x = 1
5x + y = 10
5(1) + y = 10
5 + y = 10
y = 5
10. x + 2y = 0 |×2|2x + 4y = 0
2x - 3y = 7|×1|2x - 3y = 7
________ -
7y = -7
y = -1
x + 2y = 0
x + 2(-1) = 0
x - 2 = 0
x = 2
ini saya jawab bukan ngelihat poin... tetapi karna saya bisa dalam matematika dan pesan saya semoga anda bisa mengerti dengan cara yang saya kasih ini
