tolong ya kk. terima kasih

3x - 2y =14.... pers1
2x - 5y =13.... pers2
Nilai 4x + 3y = ?

jawab:
•Eliminasi variabel x dari kedua persamaan
3x - 2y =14 |x2| 6x - 4y =28
2x - 5y =13 |x3| 6x - 15y =39
......................___________-
...................................11y = -11
................................y = -11 / 11
................................y = -1

•Subtitusi y= -1 ke persamaan 1
3x - 2y = 14
3x - 2(-1)= 14
3x + 2 = 14
3x = 14-2
3x = 12
x = 12/3
x = 4

nilai x=4 dan y=-1

4x+3y= ?
4(4) + 3(-1)
16 + (-3) = 13

JADI NILAI 4x + 3y = 13
