4x - 3y = 18 |x3| 12x - 9y = 54
------------------- -
17y = -34,,,y/q = -2...
3x + 2y = 5
3x + 2.-2 = 5
3x + -4 = 5
3x = 5 +4
x = 9 / 3
x/p = 3
Maka,, nilai dari 2p - 3q = 2.3 - 3.-2 = 6 - (-6) = 12..
Maaf kalo salah...
4x-3y=18
=12x+8y=20
=12x-9y=54
y=34
3x+2y=5
3x+2(34)=5
3x+68=5
3x=68-5
3x=63
x=63:3
2(21)-3(34)
=42-102
=60
