Kerjakanlah soal ini menggunakan metode eliminasi X dan Y 1. 6p - q = 1 4p - 3q + 4 = 0

Bab Sistem Persamaan Linear Dua Variabel

4p - 3q + 4 = 0

4p - 3q = -4 [×1]
6p - q = 1 [×3]

4p - 3q = -4
18p - 3q = 3
__________ -
-14p = -7
p = -7/-14
p = 1/2

6p + q = 1
6(1/2) + q = 1
3 + q = 1
q = 1 - 3
q = -2
