2x-5y=9 dikali 1 2x-5y=9
----------- -
-y=1
y=-1
x-3(-1)=5
x= 2
maka 3x+2y= 3(2)+2(-1)
= 4
x-3y-5 =0
x-3y = 5
y⇔ x-3y = 5 | x2 | 2x-6y = 10
2x-5y = 9 | x1 | 2x-5y = 9 _
-1y = 1
- y = 1
y = -1
x⇔ x-3y = 5
x-3.(-1) = 5
x+3 =5
x = 5-3
x = 2
maka, 3x+2y = 3.2 + 2(-1)
= 6 + (-2)
= 4
jadi, nilai dari 3x+2y adalah 4
