diketahui suatu sistem persamaan 5x + 2y = 6 dan 4x + 3y = 2 nilai 2x - 3y adalah

langsung aja y

5x + 2y = 6 (×3)
4x + 3y = 2 (×2)

15x + 6y = 18
8x + 6y = 4
__________-
7x = 14
x = 2

4x + 3y = 2
3y = 2 - 4(2)
3y = 2 - 8
3y = -6
y = -2

2x - 3y
2(2) - 3(-2)
4 + 6 = 10
jawabannya 10

semoga berguna +_+

5x + 2y = 6 || x3
4x + 3y = 2 || x2
_____________
15x + 6y = 18
8x + 6y = 4
_____________ -
7x = 14
x = 14/7
x = 2

4x + 3y = 2
4.2 + 3y = 2
8 + 3y = 2
3y = 2 - 8
3y = -6
y = -6/3
y = -2

2x - 3y
= 2.2 - 3(-2)
= 4 - (-6)
= 4 + 6
= 10
