Tentukan himpunan dari SPLDV dengan menggunakan metode subtitusi soal no 1 2x + y = 4 3x + 2y = 8 soal no 2 x + y = 8 3x + 2y = 8 tolong dijawab dong

no 1
2x + y = 4
3x + 2y =8
<=> y=-2x+4
<=> 3x + 2(-2x+4) = 8
<=> 3x - 4x +8 = 8
<=> -x=8-8
<=> x=0
<=>y=-2(0)+4
<=>y=4

HP{0,4}

Soal no 2
x+y = 8
3x + 2y =8
<=> y=-x+8
<=> 3x+2(-x+8)=8
<=>3x-2x+16=8
<=>x=8-16
<=>x=-8
<=>y=-1(-8)+8
<=>y=8+8
<=>y=16


HP{-8,16}


Sekian:)
