Semoga membantu yaaaaKELAS = 8
BAB = SPLDV
eliminasi nilai x
3x - 4y = 17 |×2
2x + 5y = -4 |×3
6x - 8y = 34
6x + 15y = -12
___________-
-23y = 46
y = 46/-23
y = -2
subtitusi nilai y
2x + 5y = -4
2x + 5(-2) = -4
2x -10 = -4
2x = -4 + 10
2x = 6
x = 6/2
x = 3
nilai 4x - 3y
= 4(3) - 3(-2)
= 12 + 6
= 18
semoga membantu
