diketahui system persamaan 4x-3y=1 dan 2x-y= -3 maka nilai 3x-2y adalah

4x - 3y = 1
2x - y = - 3 { x3 }

4x - 3y = 1
6x - 3y = - 9
__________ +
10x = 8
x = 8/10

4x - 3y = 1
16/5 - 3y = 1
- 3y = 1 - 16/5
- 3y = 5/5 - 16/5
- 3y = - 11/5
- y = - 11/5 × 3
- y = - 33/5
y = 33/5

3x - 2y
24/10 - 66/5
2,4 - 13,2
- 10,8

2x-y=-3
y=2x+3

dimasukan
4x-3(2x+3)=1
4x-6x-6=1
-2x=7
x= -3,5

4x-3y=1
4.(-3.5)-3y=1
-14-3y=1
y= -5

3x-2y =3.(-3,5)-2.(-5)
=-0,5
