Jawab:
HP = (12,0)
Penjelasan dengan langkah-langkah:
[tex]\frac{x}{3} +\frac{y}{5} =4\\\frac{5x +3y}{15} =4\\5x+3y= 60.....(persamaan 1)\\[/tex]
[tex]\frac{x}{2} + \frac{y}{4} =6\\\frac{2x+y}{4}=6\\2x+y=24.......(persamaan 2)[/tex]
2x + y = 24
y = 24 - 2x
Subtitusi y = 24 - 2x ke persamaan 1.
5x + 3y = 60
5x + 3(24 - 2x) = 60
5x + 72 - 6x = 60
-x = - 12
x = 12
Subtitusi x = 12 ke persamaan 2
2(12) + y = 24
24 + y = 24
y = 0
Jadi HP = (12,0)
