Himpunan penyelesaian dari sistem persamaan linier 5x-y-5=0 2x+y-16=0 adalah

<=> 5x - y - 5 = 0
<=> 5x - y = 5
5x = 5 + y
5x - 5 = y

<=> 2x + y - 16 = 0
<=> 2x + y = 16
2x = 16 - y
y = 16 - 2x

<=> y = y
<=> 5x - 5 = 16 - 2x
<=> 5x + 2x = 16 + 5
<=> 7x = 21
x = 3
y = 5x - 5 = 5(3) - 5 = 15 - 5 = 10
