p = 10 + l
2(10 + l) + 2l = 12
20 + 2l + 2l = 12
4l = - 8
l = - 2
p = 10 - 2 = 8
cara eliminasi:
p + l = 6
p - l = 10
_______ +
2p = 16
p = 8
l = - 2
2p +2l = 12 Ι x1 Ι 2p +2l = 12
p -l = 10 Ι x2 Ι 2p -2l = 20 -
4l = -8
l = -8/4
l = -2
2p +2l = 12
2p +2(-2) = 12
2p -4 = 12
2p = 12 +4
2p = 16
p = 16/2
p = 8
Jadi, himpunan penyelesaiannya adalah {(8,-2)}.
Itu jawabannya.
