2x+2y=2
2x-4y=14
--------------- -
6y = -12
y= -2
x+y=1
x-2=1
x=1+2
x=3
4x-3y= 4.3-3.(-2)
=12+6
= 18
2x - 4y =14I x3I 6x - 12y=42 -
18y=-36
y= -2
lalu untuk nilai x nya kita ambil pada persamaan 1
3x + 3y = 3
3x + 3.(-2) = 3
3x + (-6) = 3
3x = 3 + 6
3x = 9
x = 3
lalu nilai
4x-3y
4.3-3.(-2 )
12- (-6)
18
jadi nilainya 18
semoga membantu
